MAX38902E

14μVRMS Low Noise 500mA LDO Linear Regulator

14μVRMS, Low-Noise, Low-Dropout, 500mA Linear Regulators in a 2mm x 2mm TDFN Package


Please check latest availability status for a specific part variant.

Description

The MAX38902E is low-noise linear regulator that delivers up to 500mA of output current with only 14μVRMS of output noise from 10Hz to 100kHz. This regulator maintains ±1% output accuracy over a wide input voltage range, requiring only 100mV of input-to-output headroom at full load. The 600µA no-load supply current is independent of dropout voltage.

The MAX38902E has a resistor adjustable output voltage in the range of 0.8V to 5.0V and includes an active-low POK output. The device features a programmable output soft-start rate, output over-current and thermal overload protection.

The MAX38902E is offered in an 8-pin TDFN package.
