MC33264
MC33264 is Voltage Regulators manufactured by onsemi.
Micropower small CAP™ Voltage Regulators with
On/Off Control
The MC33264 series are micropower low dropout voltage regulators available in SO- 8 and Micro- 8 surface mount packages and a wide range of output voltages. These devices 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.
