MIC5206-5.0YM5-TR Microchip

MIC5206 150mA Low-Noise LDO Regulator General Description Features The MIC5206 is an efficient linear voltage regulator with Error flag indicates undervoltage fault very low dropout voltage (typically 17mV at light loads and High output voltage accuracy 165mV at 150mA), and very low ground current (600A at Guaranteed 150mA output 100mA output), with better than 1% initial accuracy. It has Ultra-low-noise output (8-pin versions) a logic compatible enable/shutdown control input and an internal undervoltage monitor. Low quiescent current Low dropout voltage Designed especially for hand-held, battery-powered devices, the MIC5206 can be switched by a CMOS or TTL Extremely tight load and line regulation compatible logic signal. When disabled, power Very low temperature coefficient consumption drops nearly to zero. Dropout ground current Current and thermal limiting is minimized to prolong battery life. Reversed-battery protection Key features include an undervoltage monitor with an error Zero off-mode current flag output, a reference bypass pin to improve its already Logic-controlled electronic enable low-noise performance (8-pin versions only), reversed- battery protection, current limiting, and overtemperature shutdown. Applications The MIC5206 is available in several fixed voltages in a tiny Cellular telephones SOT-23-5 package. It features a pinout, similar to the Laptop, notebook, and palmtop computers LP2980, but has significantly better performance. Fixed Battery-powered equipment and adjustable output voltage versions, featuring the PCMCIA V and V regulation/switching reference bypass option, are available in the 8-pin Micrel CC PP Mini 8 8-pin MSOP (micro small-outline package). Consumer/personal electronics SMPS post-regulator/dc-to-dc modules For low-dropout regulators that are stable with ceramic output capacitors, see the Cap MIC5245/6/7 family.
