MIC5247 150mA Low-Voltage µCap Linear Regulator

The MIC5247 is an ef,cient and 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 speci,cally for handheld and battery-powered de- vices, the MIC5247 provides a Logic compatible enable pin. When disabled, power consumption drops nearly to zero. The MIC5247 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld Wireless devices. By Micrel Semiconductor
