MAX8902AATA+ [Maxim]

The MAX8902A/MAX8902B are low-noise linear regulators that deliver up to 500mA output current with only 16µVRMS output noise over a 100kHz bandwidth. They maintain output voltage over a wide input range (1.7V to 5.5V) with only 100mV input-to-output headroom at full load. The regulators feature a low 80µA typical supply current, independent of load current and dropout voltage. Control circuitry includes programmable soft-start, short-circuit, reverse current, and thermal-overload protection. Additional features include an enable input and a power-OK output (MAX8902B only). Output voltage can be set via pin-selectable inputs (MAX8902A) or external resistor divider (MAX8902B).
