Maxim Integrated MAX25302A/B 2A Automotive LDO Linear Regulators

Maxim Integrated MAX25302A/B 2A Automotive LDO Linear Regulators are 1.7V–5.5V VIN, low-noise linear regulators. The regulators deliver up to 2A of output current with only 5.1μVRMS of output noise from 10Hz to 100kHz. They maintain ±1% output accuracy over a wide input voltage range, requiring only 100mV of input-to-output headroom at full load. The 1.3mA no-load supply current is independent of dropout voltage.
