Overview
The ADM7150 is a low dropout (LDO) linear regulator that operates from 4.5 V to 16 V and provides up to 800 mA of output current. Using an advanced proprietary architecture, it provides high power supply rejection (>90 dB from 1 kHz to 1 MHz), ultralow output noise (<1.7 nV√Hz), and achieves excellent line and load transient response with a 10 µF ceramic output capacitor.
- 0 µV rms total integrated noise from 100 Hz to 100 kHz 1.6 µV rms total integrated noise from 10 Hz to 100 kHz Noise spectral density: 1.7 nV√Hz typical from 10 kHz to 1 MHz Power supply rejection ratio (PSRR) at 400 mA load >90 dB from 1 kHz to 100 kHz, VOUT = 5 V >60 dB at 1 MHz, VOUT = 5 V Dropout voltage: 0.6 V at VOUT = 5 V, 800 mA load Initial voltage accuracy: ±1% Voltage accuracy over line, load and temperature: ±2% Quiescent current (IGND): 4.3 mA at no load Low shutdown current: 0.1 µA Stable with a 10 µF ceramic output capacitor Fixed output voltage options: 1.8 V, 2.8 V, 3.0 V, 3.3 V, 4.5 V, 4.8 V, and 5.0 V (16 outputs between 1.5 V and 5.0 V are available) Exposed pad 8-lead LFCSP and 8-lead SOIC packages
