Overview
The ADP7104ACPZ-R7 is a CMOS, low dropout linear regulator (LDO) produced by Analog Devices Inc. This high input voltage LDO operates from 3.3V to 20V and provides up to 500mA of output current, making it ideal for regulating high performance analog and mixed-signal circuits. The device features an advanced proprietary architecture that ensures high power supply rejection, low noise, and excellent line and load transient response with a small 1µF ceramic output capacitor.
The ADP7104ACPZ-R7 includes a digital power-good output for monitoring the health of the output voltage and a user-programmable precision under-voltage lockout (UVLO) function for sequencing multiple power supplies. It is available in an 8-lead LFCSP package, offering a compact solution with excellent thermal performance.
