AiT Semiconductor Inc. www.ait-ic.com A6301A LOW DROPOUT VOLTAGE REGULATOR 300mA LOW DROPOUT CMOS VOLTAGE REGULATORS REV1.1 - JUL 2014 RELEASED, MAY 2017 UPDATED - - 1 - DESCRIPTION FEATURES The A6301A series are highly precise, low power consumption, positive voltage regulators manufactured using CMOS and laser trimming technologies. The series provides large currents with a significantly small dropout voltage. The A6301A consists of a current limiter circuit, a driver transistor, a precision reference voltage and an error amplifier. Output voltage is selectable in 0.1V steps between 1.2V ~ 6.0V. The A6301A is available in SOT-23, SOT -25 and SOT89-3 packages.
