ADM7171ACPZ-1.8 Integrated Circuit Chip 1A Low Dropout Linear Regulator 6.5V CMOS LDO

ADM7171ACPZ-1.8 Integrated Circuit Chip 1A Low Dropout Linear Regulator 6.5V CMOS LDO​

Product Description Of ADM7171ACPZ-1.8

ADM7171ACPZ-1.8 is a CMOS, low dropout linear regulator (LDO) that operates from 2.3 V to 6.5 V and provides up to 1 A of output current. This high output current LDO is ideal for regulation of high performance analog and mixed signal circuits operating from 6 V down to 1.2 V rails.
Using an advanced proprietary architecture, the ADM7171ACPZ-1.8 provides high power supply rejection and low noise, and achieves excellent line and load transient response with just a small 4.7 μF ceramic output capacitor. Load transient response is typically 1.5 μs for a 1 mA to 500 mA load step.
