AP7201

DISCONTINUED AP7201 DUAL 150mA LOW DROPOUT LINEAR REGULATOR Features General Description Wide input voltage range: 1.9V – 5.5V Low dropout voltage: 100mV at 100mA output current Very low quiescent current (Iq): 25uA typical Fixed output voltage: 1.0V to 3.3V Up to 150mA per output channel Very fast transient response High PSRR: 78dB at 1kHz Accurate voltage regulation 300mA current limiting Thermal shutdown protection Ambient temperature range -40ºC to 85°C Package available: DFN2018-6 (USP-6B) DFN2018-6 (USP-6B): Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish / RoHS Compliant (Note 1) The AP7201 is a dual low-dropout (LDO) CMOS linear regulator. The device operates from 1.9V to 5.5V input and delivers up to 150mA per output channel. The AP7201 includes a pass element, voltage reference, error amplifier, current limit and built-in phase compensation. Key features include individual logic-compatible enable/shutdown control inputs, fold-back current limit and thermal shutdown protections. The AP7201 is fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. The fixed output voltage for each channel is set independently. Voltages are 100mV per step within a range of 1.0V to 3.3V. The EN function allows the output of each channel to be turned off independently, resulting in greatly reduced power consumption. The AP7201 is available in the DFN2018-6 (USP-6B) package. Applications Cell ...
