AP451SLA

Voltage Regulators - Linear Regulator Controllers Overview

The AP451SLA is a dual-output linear regulator controller manufactured by Diodes Incorporated. It operates within an input voltage range of 2.7V to 16V and supports output currents up to 300mA per channel. The device features two independent low-dropout regulators with fixed output voltages, typically 3.3V and 5V, housed in an 8-SOIC package. Key electrical characteristics include a maximum quiescent current of 150µA and a shutdown current of less than 1µA. It includes built-in protection against overcurrent, thermal overload, and reverse battery conditions.
