MIC39101-1.8BM Description

Short technical summary and product information.

The MIC39101-1.8BM from Micrel Inc. is a 1A low-dropout linear voltage regulator designed for low-voltage, high-current applications. It utilizes a proprietary Super βeta PNP™ pass element, resulting in extremely low dropout voltage, typically 410mV at 1A, and low ground current, typically 11mA at 1A. This regulator is ideal for applications requiring voltage conversion, such as from 3.3V to 2.5V or 2.5V to 1.8V.

Key features include a guaranteed minimum output current of 1A, 1% initial accuracy, and protection against overcurrent, thermal shutdown, and reversed battery conditions. The MIC39101 series is available in a thermally enhanced power 8-lead SOIC package, suitable for surface mount applications. The device also includes an enable pin for control and an open-collector error flag output.

This regulator is well-suited for PC add-in cards, PowerPC™ power supplies, high-efficiency linear power supplies, SMPS post regulators, multimedia and PC processor supplies, battery chargers, and low-voltage microcontrollers and digital logic. Its low-profile package and robust protection features make it a reliable choice for demanding designs.
