ADI ADPL42005CPZ-REDYKIT RedyKits™ Evaluation Board For ADPL42005 Low Dropout Linear Regulator
Shenzhen Mingjiada Electronics Co., Ltd., as a trusted supplier of electronic components, now offers the genuine ADI ADPL42005CPZ-REDYKIT RedyKits™ evaluation board. This kit provides a comprehensive solution for evaluating and prototyping the ADPL42005 series of high-performance low-dropout (LDO) linear regulators, enabling engineers to rapidly validate and integrate low-noise power supplies while accelerating time-to-market.
【Core Overview of the ADPL42005CPZ-REDYKIT Evaluation Kit】
The ADPL42005CPZ-REDYKIT is a RedyKits™ evaluation kit specifically designed to simplify prototyping and performance evaluation of the ADPL42005, a 20V, 500mA low-noise CMOS LDO linear regulator.
The ADPL42005CPZ-REDYKIT features a compact, comprehensive design:
Core Evaluation Board: The kit includes one EVAL-ADPL42005CP-AZ evaluation board, pre-configured to deliver a fixed 3.3V output.
Extensive Voltage Options: Six ADPL42005 LFCSP-packaged chips with different voltage options are supplied with the board, facilitating flexible evaluation and replacement.
Ready-to-Use Design: Power-up and testing are possible immediately upon unboxing, eliminating the need for users to solder core components or build peripheral circuits, thereby significantly simplifying the evaluation process.
Compared to the alternative version bearing ‘RDZ’ in its kit name (utilising SOIC packaging), the CPZ variant is specifically engineered for the ADPL42005 chip in its 8-pin (3mm x 3mm) LFCSP compact package, making it more suitable for applications with stringent space constraints.
【ADPL42005CPZ-REDYKIT Evaluation Kit Design Philosophy】
Traditional evaluation boards typically offer only a single output voltage option, such as 3.3V. Should users require evaluation of other voltages (e.g., 2.5V or 1.8V), they must purchase corresponding chips and evaluation boards separately. This not only increases costs and lead times but also complicates systematic performance comparisons.
The ADPL42005CPZ-REDYKIT RedyKits™ revolutionises this process. This kit is not merely a circuit board but a complete evaluation solution. It includes a fully assembled and tested evaluation board alongside the full range of voltage option chips for this series, enabling users to rapidly and comprehensively evaluate the ADPL42005's performance across different output voltages.
【The Core Enabler of ADPL42005CPZ-REDYKIT: Exceptional Performance of the ADPL42005 LDO Linear Regulator】
The ADPL42005 LDO regulator targeted by this ADPL42005CPZ-REDYKIT evaluation board is a high-performance product from ADI designed for noise-sensitive applications. Its key performance parameters are as follows:
1. Wide-range and high-precision power supply
Input voltage range: 4V to 20V, compatible with multiple industrial and communications power buses.
Output current capability: Up to 500mA, providing ample power for complex analogue and mixed-signal circuits.
Ultra-high output accuracy: Initial accuracy of ±0.8%, with total accuracy maintained between -2% and +1% across the full temperature range of -40°C to 125°C, ensuring extreme power supply reliability.
2. Exceptional Noise Suppression and Pure Output
Ultra-low output noise: Noise voltage as low as 32µVrms, independent of output voltage, providing a ‘silent’ background for precision circuits.
High power supply rejection ratio (PSRR): PSRR up to 58dB at 10kHz, effectively filtering high-frequency ripple interference from upstream switching power supplies.
3. Comprehensive Management and Protection Features
Programmable Enable/Undervoltage Lockout (UVLO): Users can precisely set the start-up voltage threshold via an external resistor, enabling orderly power-up sequencing in multi-power systems.
Power Good (PG) Signal: Provides a digital output signal for real-time monitoring of output voltage status, facilitating system-level diagnostics and management.
Multiple Safety Protections: Integrated reverse current protection, foldback current limiting, and thermal overload protection safeguard the regulator and downstream loads under various abnormal conditions.
【ADPL42005CPZ-REDYKIT Evaluation Board Design Highlights and Flexible Configuration】
The ADPL42005CPZ-REDYKIT evaluation board transcends being merely a chip carrier; its meticulous design significantly enhances evaluation experience and design flexibility:
Convenient Test Interfaces: Key test points including VIN, VOUT, GND, and PG (Power Good) are brought out on the board, enabling engineers to directly monitor power status, measure voltage drop, and assess dynamic response using an oscilloscope or multimeter.
Enable (EN) Control: A jumper allows selection between keeping the regulator permanently powered or connecting it to an external interface for remote switch control.
Output Voltage Configuration: Jumpers enable selection between using the on-board resistor voltage divider network (setting the adjustable version to 3.3V) or connecting the feedback pin directly to the output (emulating fixed-output mode). Users may also solder an optional RC network to achieve the same low-noise performance as the fixed-output version with the adjustable variant.
Thermal Optimisation Design: The evaluation board fully accounts for the ADPL42005's thermal requirements at full 500mA output. The PCB layout facilitates chip dissipation, ensuring evaluation results accurately reflect the device's performance in practical applications.
【Target Application Areas for ADPL42005CPZ-REDYKIT】
With its high performance and evaluation convenience, the ADPL42005CPZ-REDYKIT kit serves as an ideal starting point for power supply designs in the following cutting-edge fields:
High-Speed Data Conversion and Precision Analogue Front-Ends: The ADPL42005CPZ-REDYKIT delivers ultra-clean power to high-speed ADCs (analogue-to-digital converters), DACs (digital-to-analogue converters), and precision operational amplifiers, ensuring optimal signal-to-noise ratio (SNR) and effective number of bits (ENOB).
Communications and Network Infrastructure: Deployed in base stations, optical modules, routers and similar equipment, the ADPL42005CPZ-REDYKIT powers clock generators (e.g., PLL/VCO), high-speed SerDes and RF units, reducing phase noise and bit error rates.
