Description

General part information

MIC5255 Series

The MIC5255 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 MIC5255 provides a very-low noise output, ideal for RF applications where a clean voltage source is required. A noise bypass pin is also available for further reduction of output noise.

Designed specifically for handheld and battery-powered devices, the MIC5255 provides a TTL logic-compatible enable pin. When disabled, power consumption drops nearly to zero.

The MIC5255 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices.
