MAX15028ATB-T Datasheet

1.425V to 3.6V Input, 1A Low-Dropout Regulators with BIAS Input


General Description
The MAX15027/MAX15028 low-dropout linear regulators operate from input voltages as low as 1.425V and deliver up to 1A of continuous output current with a typical dropout voltage of only 75mV. The output voltage is adjustable from 0.5V to VIN and is ±2% accurate over load and line variations, from -40°C to +125°C. The MAX15028 features a BIAS input of 3V to 5.5V from an always-on power supply. The BIAS input current is reduced down to less than 2µA during shutdown
