MC33264 Datasheet | Motorola Semiconductor

feature a very low quiescent current (100 µA in the ON mode; 0.1 µA in the OFF mode), and are capable of supplying output currents up to 100 m A. Internal current and thermal limiting protection is provided. They require only a small output capacitance for stability. Additionally, the MC33264 has either active HIGH or active LOW control (Pins 2 and 3) that allows a logic level signal to turn- off or turn- on the regulator output. Due to the low input- to- output voltage differential and bias current specifications, these devices are ideally suited for battery powered puter, consumer, and industrial equipment where an extension of useful battery life is desirable.
