ADM7171 datasheet


The ADM7171 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 device 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.

Typical Circuit :



1. Input voltage range: 2.3 V to 6.5 V

2. Maximum load current: 1 A

3. Fast transient response: 1.5 μs for 1 mA to 500 mA load step 60 dB PSRR at 100 kHz

4. Stable with small 4.7 μF ceramic output capacitor

5. Adjustable and fixed output voltage options: 1.2 V to 5.0 V
