Microchip | MIC5213-2.5YC5-TR

The MIC5213-2.5YC5 TR is a µCap 80 mA linear voltage regulator in the Teeny™ SC-70 package. Featuring half the footprint of the standard SOT-23 package, this Teeny™ SC-70 regulator has very low dropout voltage (typically 20 mV at light loads and 300 mV at 80 mA) and very low ground current (225 µA at 20 mA output). It also offers better than 3% initial accuracy and includes a logic-compatible enable input. The µCap regulator design is optimized to work with low-value, low-cost ceramic capacitors. The outputs typically require only 0.47 µF of output capacitance for stability.

Designed especially for hand-held, battery-powered devices, the MIC5213 can be controlled by a CMOS or TTL compatible logic signal. When disabled, power consumption drops nearly to zero. If on-off control is not required, the enable pin may be tied to the input for 3-terminal operation. The ground current of the MIC5213 increases only slightly in dropout, further prolonging battery life. Key MIC5213 features include current limiting, overtemperature shutdown, and protection against reversed battery.
