Supply TI Original TPS7A8500RGRR Low Noise, Low Dropout Linear Regulator

Shenzhen Mingjiada Electronics Co., Ltd.——Long Term Supply TI (TPS7A8500RGRR) 4A, low-VIN, low-noise, ultra-low-dropout voltage regulator with power good with high-accuracy.

TPS7A8500RGRR is a low-noise (4.4 µVRMS), low-dropout linear regulator (LDO) capable of sourcing 4 A with only 240 mV of maximum dropout.

TPS7A8500RGRR output voltage is pin-programmable from 0.8 V to 3.95 V and adjustable from 0.8 V to 5.0 V using an external resistor divider.

TPS7A8500RGRR——The combination of low-noise (4.4 µVRMS), high-PSRR, and high output current capability makes the TPS7A8500RGRR ideal to power noise-sensitive components such as those found in high-speed communications, video, medical, or test and measurement applications.

The high performance of the TPS7A8500RGRR limits power-supply-generated phase noise and clock jitter, making this device ideal for powering high-performance serializer and deserializer (SerDes), analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and RF components. Specifically, RF amplifiers benefit from the high-performance and 5.0-V output capability of the device.

The TPS7A8500RGRR, with its outstanding parameter specifications, is an ideal choice for power supply chains in precision instruments, communication equipment, medical electronics, industrial control, and portable devices:

Ultra-low Dropout: The core advantage of the TPS7A8500RGRR lies in its extremely low voltage drop. When delivering up to 2A of output current, its voltage drop is as low as 65mV typical (maximum 130mV @ 2A). This means that even when the input voltage is only slightly higher than the output voltage, the TPS7A8500RGRR can still operate stably and efficiently, significantly reducing system power consumption and thermal requirements, making it particularly suitable for battery-powered applications or those with limited input voltage margins.

Wide input voltage range: The TPS7A8500RGRR supports a wide input voltage range of 0.7V to 5.5V, compatible with various low-voltage power rails (such as lithium batteries, single/multiple cells, low-voltage buses), offering exceptional design flexibility.

High-precision output: Across the entire load, line, and temperature range, the TPS7A8500RGRR delivers output voltage accuracy of up to ±1%, ensuring an extremely clean and stable voltage reference for noise-sensitive core components such as FPGAs, ASICs, DSPs, microprocessor cores, high-speed ADCs/DACs, and RF modules.

Low Noise and High PSRR: The TPS7A8500RGRR features excellent noise suppression capability (as low as 13μVRMS) and a power supply rejection ratio (PSRR) of up to 75dB (1kHz), effectively filtering out ripple and noise on the input power supply to provide a ‘quiet’ power environment for downstream circuits.

High integration and small package: The TPS7A8500RGRR is housed in a compact 3mm x 3mm VQFN (RGR) package (RGRR denotes reel-to-reel packaging) and integrates a wealth of features, including enable control, power good (PG) signal output, short-circuit protection, and thermal shutdown protection, simplifying peripheral circuits and saving valuable PCB space.

Low static current: In light load or standby modes, the TPS7A8500RGRR's low static current characteristics help extend battery life.

TPS7A8500RGRR Key Application Areas
Thanks to its outstanding features such as ultra-low voltage drop, high precision, and low noise, the TPS7A8500RGRR is widely used in scenarios with extremely high power quality requirements:
Portable and battery-powered devices: smartphones, tablets, wearable devices, handheld terminals, portable medical devices (such as blood glucose monitors, patient monitors), maximising battery efficiency.
