Product Details

The MAX8902A/MAX8902B low-noise linear regulators deliver up to 500mA of output current with only 16µVRMS of output noise in a 100kHz bandwidth. These regulators maintain their output voltage over a wide input range, requiring only 100mV of input-to-output headroom at full load.

These LDOs maintain a low 80µA typical supply current, independent of the load current and dropout voltage. The regulator control circuitry includes a programmable soft-start circuit and short circuit, reverse current, and thermal-overload protection. Other features include an enable input and a power-OK output (MAX8902B only).

The MAX8902A output voltage can be set to 1.5V, 1.8V, 2.0V, 2.5V, 3.0V, 3.1V, 3.3V, 4.6V, or 4.7V using the SELA and SELB inputs. The MAX8902B output voltage can be set between 0.6V and 5.3V with an external resistor voltage-divider.
