MIC5258 Datasheet | Micrel Semiconductor

Micrel, Inc. 150m A µCap CMOS LDO Regulator w/Power Good General Description The MIC5258 is an efficient, precise CMOS voltage regulator with power good output. The MIC5258 offers better than 3% initial accuracy, and constant ground current (typically 100µA)over load . The MIC5258 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. Key Features include current limit, thermal shutdown, a pushpull output for faster transient response, and an active clamp to speed up device turnoff. Available in the Itty Bitty™ SOT-23-5 package, the MIC5258 is a fixed 1.2V regulator. Features - Power Good indicator - Load independent, ultralow ground current: 100µA - 150m A output current - Current limiting - Thermal shutdown - Tight load and line regulation - “Zero” off-mode current - Stability with low-ESR capacitors - Fast transient response - TTL-Logic-controlled enable input Applications - Processor power-up sequencing - Laptop, notebook, and palmtop puters - PCMCIA VCC and VPP regulation/switching Typical Application Part Number Standard Marking Pb-Free Marking MIC5258-1.2BM5 LN12 MIC5258-1.2YM5 KN12 - Other voltages available.
