MIC5236-3.3BMM集成电路（IC）的线性+开关稳压器规格书PDF中文资料

General Description

The MIC5236 is a low quiescent current, µCap low-dropout regulator. With a maximum operating input voltage of 30V and a quiescent current of 20µA, it is ideal for supplying keep-alive power in systems with high-voltage batteries.

Capable of 150mA output, the MIC5236 has a dropout voltage of only 300mV. It can also survive an input transient of –20V to +60V.

Features

• Ultra-low quiescent current (IQ = 20µA @IO = 100µA)

• Wide input range: 2.3V to 30V

• Low dropout:

230mV @50mA;

300mV @150mA

• Fixed 2.5V, 3.0V, 3.3V, 5.0V, and Adjustable outputs

• ±1.0 initial output accuracy

• Stable with ceramic or tantalum output capacitor

• Load dump protection: –20V to +60V input transient survivability

• Logic compatible enable input
