Device Overview

Summary

The MIC5234 is a low-quiescent current, µCap low-dropout regulator. With a maximum operating input voltage of 30V and quiescent current of 20µA, it is ideal for supplying keep-alive power in systems with high-voltage batteries.

Capable of 150mA output, the MIC5234 has a dropout voltage of only 320mV. It can also survive an input transient of -20V to +32V. The MIC5234 requires only a 2.2µF output capacitor for stable operation.

The MIC5234 includes a logic-compatible enable input. Other features of the MIC5234 include thermal shutdown, load dump protection, and reverse leakage and reverse battery protection.

The MIC5234 is available in an 8-pin ePad SOIC package with a junction operting range from -40°C to +125°C.
