MIC5206 Datasheet | Micrel Semiconductor

Micrel 150m A Low-Noise LDO Regulator General Description The MIC5206 is an efficient linear voltage regulator with very low dropout voltage (typically 17m V at light loads and 165m V at 150m A), and very low ground current (600µA at 100m A output), with better than 1% initial accuracy. It has a logic patible enable/shutdown control input and an internal undervoltage monitor. Designed especially for hand-held, battery-powered devices, the MIC5206 can be switched by a CMOS or TTL patible logic signal. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to prolong battery life. Key Features include an undervoltage monitor with an error flag output, a reference bypass pin to improve its already lownoise performance (8-lead versions only), reversed-battery protection, current limiting, and overtemperature shutdown. The MIC5206 is available in several fixed voltages in a tiny SOT-23-5 package. It Features a pinout, similar to the LP2980, but has significantly better performance. Fixed and adjustable output voltage versions, featuring the reference bypass option, are available in the 8-lead Micrel Mini 8™ 8-lead MSOP (micro small-outline package).
