Micrel Teeny™ SC-70 µCap Low-Dropout Regulator Final Information General Description The MIC5213 is a µCap 80m A 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 20m V at light loads and 300m V at 80m A) and very low ground current (225µA at 20m A output). It also offers better than 3% initial accuracy and includes a logic-patible enable input. The µCap regulator design is optimized to work with lowvalue, low-cost ceramic capacitors. The outputs typically require only 0.47µF of output capacitance for stability. Designed especially for hand-held, battery-powered devices, the MIC5213 can be controlled by a CMOS or TTL patible 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. The MIC5213 is available in 2.5V, 2.6V, 2.7V, 2.8V, 3.0V, 3.3V, 3.6V, and 5.0V fixed voltages. Other voltages are available; contact Micrel for details.
