ADP223 - High PSRR Voltage Regulators

Download the ADP223 datasheet PDF. This datasheet also covers the ADP222 variant, as both devices belong to the same high psrr voltage regulators family and are provided as variant models within a single manufacturer datasheet.

Description

The 300 mA, adjustable dual output ADP223/ADP225 and fixed dual output ADP222/ADP224 combine high PSRR, low noise, low quiescent current, and low dropout voltage in a voltage regulator that is ideally suited for wireless applications with demanding performance and board space requirements.

Features

  • Input voltage range: 2.5 V to 5.5 V Small, 8-lead, 2 mm × 2 mm LFCSP package Initial accuracy: ±1% High PSRR: 70 dB at 10 kHz, 60 dB at 100 kHz, 40 dB at 1 MHz Low noise: 27 µV rms at VOUT = 1.2 V, 50 µV rms at VOUT = 2.8 V Excellent transient response Low dropout voltage: 170 mV at 300 mA load 65 µA typical ground current at no load, both LDOs enabled Fixed output voltage from 0.8 V to 3.3 V (ADP222/ADP224) Adjustable output voltage range from 0.5 V to 5.0 V (ADP223/ADP225) Quick output dischar.
