1 / 8 page August 2004 1 MIC5213 MIC5213 Micrel General Description The MIC5213 is a µCap 80mA 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 20mV at light loads and 300mV at 80mA) and very low ground current (225 µA at 20mA 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. 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.
