MIC5206

MIC5206 Micrel MIC5206 150mA Low-Noise LDO Regulator General Description The MIC5206 is an efficient linear voltage regulator with very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and very low ground current (600µA at 100mA output), with better than 1% initial accuracy. It has a logic compatible 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 compatible 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). Features Error flag indicates undervoltage fault High output voltage accuracy Guaranteed 150mA output Ultra-low-noise output (8-lead versions) Low quiescent current Low dropout voltage Extremely tight load and line regulation Very low temperature coefficie...
