MIC5239-3.3BMM Description

Short technical summary and product information.

The MIC5239-3.3BMM from Micrel Inc. is a µCap low-dropout linear regulator designed for applications requiring low quiescent current and high output current capability. It can supply a continuous 500mA with a low dropout voltage of 350mV at 500mA.

This regulator operates from an input voltage range of 2.3V to 30V, making it suitable for systems with high voltage batteries. Key electrical features include ±1.0% initial output accuracy, ultra-low quiescent current of 23µA, and stability with ceramic or tantalum output capacitors requiring only a 3.3µF capacitor.

Protection features include overcurrent protection, thermal shutdown, overvoltage shutdown, reverse-leakage protection, and reverse-battery protection. The MIC5239-3.3BMM includes a logic-compatible enable input and an undervoltage error flag indicator.

Available in a thermally enhanced 8-MSOP package, this device is ideal for applications such as USB power supplies, keep-alive supplies in portable computers, logic supplies from high voltage batteries, and automotive electronics.
