Description

The MIC5253 is an efficient, CMOS voltage regulator opti- mized for ultra-low-noise applications. MIC5253-2.6BC5 offers 1.5% initial accuracy, extremely low dropout voltage (165mV at 100mA), and low ground current (typically 95µA at full load). The MIC5253 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 de- vices, the MIC5253 provides a TTL-logic-compatible enable pin. When disabled, power consumption drops nearly to zero. The MIC5253 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices. Available in the Teeny™ SC-70-5 package, the MIC5253 offers a  wide range of output voltages. Key features include current limit, thermal shutdown, faster transient response, and an active clamp to speed up device turn-off.
