MIC5258 - 150mA UCap CMOS LDO Regulator w/Power Good
Overview
The MIC5258 is a high-efficiency, accurate CMOS regulated power-good output. The MIC5258 provides better than 3% initial accuracy and is constantly overloaded with current (typically 100µA). The MIC5258 also features low ESR ceramic capacitors, critical for reducing the amount of power necessary to reduce board space in handheld wireless devices. Key features include current limit, thermal shutdown, pushpull for faster transient response, output and active clamp to speed up device off-putting. Available in IttyBitty™ in a SOT-23-5 package, the MIC5258 is a fixed 1.2V regulator.
