MIC5247

The MIC5247 is an efficient, precise low voltage CMOS voltage regulator optimized for ultra-low-noise applications. The MIC5247 offers better than 1% initial accuracy, and 85A constant ground current over load (typically 85A). The MIC5247 provides a very low noise output, ideal for RF applications where quiet voltage sources are required. A noise bypass pin is also available for further reduction of output noise.

Designed specifically for hand-held and battery-powered devices, the MIC5247 provides a logic compatible enable  pin.When disabled, power  onsumption drops nearly to zero.The MIC5247 also works with low-ESR ceramic  apacitors,reducing the amount of board space necessary for power
applications, critical in hand-held wireless devices.Key features include current limit, thermal shutdown, a pushpull output for faster transient response, and an active clamp to speed up device turnoff. Available in the IttyBitty™ SOT-23-5 package, the MIC5247 also offers a range of fixed output voltages.
