Analog Devices / Maxim Integrated MAX25301A/B Automotive LDO Linear Regulators

Analog Devices Inc. MAX25301A/B Automotive LDO Linear Regulators deliver up to 1A of output current with only 7µVRMS of output noise from 10Hz to 100kHz. The regulators maintain ±1% output accuracy over a wide input-voltage range. The LDO linear regulators require only 100mV of input-to-output headroom at full load. The 1200µA no-load supply current is independent of dropout voltage.
