Analog Devices / Maxim Integrated MAX38902 LDO Linear Regulators

Analog Devices MAX38902 LDO Linear Regulators deliver up to 500mA of output current with only 12μV_RMS of output noise from 10Hz to 100kHz. The regulators maintain ±1% output accuracy over a wide input voltage range. The Analog Devices MAX38902 requires only 100mV of input-to-output headroom at full load. The 365μA no-load supply current is independent of drop-out voltage. The regulators include a programmable output soft-start rate, output overcurrent, and thermal overload protection.
