MIC5252 Datasheet | Micrel Semiconductor

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 (135m V at 150m A) 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-patible enable 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...
