The MIC5249 is an efficient, precise 300mA CMOS voltage regulator with power-on reset delay which can be implemented via an external capacitor. It offers 1% initial accuracy, extremely low dropout voltage (typically 400mV @ 300mA), and low ground current (typically 85mA) over load.
Designed specifically for noise-critical applications in handheld or battery-powered devices, the MIC5249 comes equipped with a noise reduction feature to filter the output noise via an external capacitor. Other features of the MIC5249 include a logic-compatible 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 handheld wireless devices.
