MIC5249 Datasheet | Micrel Semiconductor

300m A µCap LDO with Programmable Power-On Reset Delay General Description The MIC5249 is an efficient, precise 300m A CMOS voltage regulator with power on reset (POR) delay which can be implemented via an external capacitor. It offers 1% initial accuracy, extremely low dropout voltage (typically 400m V @ 300m A), and low ground current (typically 85m A) over load. Designed specifically for noise-critical applications in handheld or battery-powered devices, the MIC5249 es equipped with a noise reduction feature to filter the output noise via an external capacitor. Other Features of the MIC5249 include a logic-patible enable pin, current limit, thermal shutdown, ultra-fast transient response, and an active clamp to speed up device turnoff. The MIC5249 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The MIC5249 is available in the MSOP-8 package. Data sheets and support...
