Product introduction

The MAX25300AATA is a low-noise linear regulator that delivers up to 500mA of output current and only 12μVRMS of output noise in the frequency range of 10Hz to 100kHz. The MAX25300AATA regulator maintains ±1% output accuracy over a wide input voltage range and requires only 100mV input-output margin at full load. 365μA no load power supply current does not affect the pressure difference.

The MAX25300AATA has nine pin selectable output voltages: 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 4.0V and 5V. The regulator is available in an 8-pin TDFN package.
