ADP7104 - CMOS LDO

Description

The ADP7104 is a CMOS, low dropout linear regulator that operates from 3.3 V to 20 V and provides up to 500 mA of output current.

This high input voltage LDO is ideal for regulation of high performance analog and mixed‐signal circuits operating from 19 V to 1.22 V rails.

Features

  • Input voltage range: 3.3 V to 20 V.
  • Maximum output current: 500 mA.
  • Low noise: 15 µV rms for fixed output versions.
  • PSRR performance of 60 dB at 10 kHz, VOUT = 3.3 V.
  • Reverse current protection.
  • Low dropout voltage: 350 mV at 500 mA.
  • Initial accuracy: ±0.8%.
  • Accuracy over line, load, and temperature.
  • 2% to +1%, TJ =.
  • 40°C to +125°C.
  • 1.25% to +1%, TJ = 0°C to +85°C.
  • Low quiescent current (VIN = 5 V), IGND = 900 μA w.
