1 / 9 page MIC5252 Micrel, Inc. February 2005 1 M9999-020305 General Description The MIC5252 is an efficient, precise CMOS voltage regulator optimized for ultra-low-noise applications. It offers 1% initial accuracy, extremely-low dropout voltage (135mV at 150mA) and low ground current (typically 90µA). The MIC5252 provides a very-low-noise output, ideal for RF applications where a clean voltage source is required. The MIC5252 has a high PSRR even at low supply voltages, critical for battery operated electronics. A noise bypass pin is also available for further reduction of output noise. Designed specifically for handheld and battery-powered devices, the MIC5252 provides a TTL-logic-compatible en- able pin. When disabled, power consumption drops nearly to zero. The MIC5252 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices. Key features include current limit, thermal shutdown, faster transient response, and an active clamp to speed up device turn-off. The MIC5252 is available in the 6-pin 2mm × 2mm MLF™ package and the IttyBitty® SOT-23-5 package in a wide range of output voltages.
