LAx MIC5213 Micrel MIC5213 Teeny SC-70 Cap Low-Dropout Regulator Final Information General Description Features The MIC5213 is a Cap 80mA linear voltage regulator in the Teeny SC-70 package Teeny SC-70 package. Featuring half the footprint of the Wide selection of output voltages standard SOT-23 package, this Teeny SC-70 regulator Guaranteed 80mA output has very low dropout voltage (typically 20mV at light loads Low quiescent current and 300mV at 80mA) and very low ground current (225 A at Low dropout voltage 20mA output). It also offers better than 3% initial accuracy Tight load and line regulation and includes a logic-compatible enable input. Low temperature coefficient Current and thermal limiting The Cap regulator design is optimized to work with low- Reversed input polarity protection value, low-cost ceramic capacitors. The outputs typically Zero off-mode current require only 0.47 F of output capacitance for stability. Logic-controlled shutdown Designed especially for hand-held, battery-powered devices, Stability with low ESR ceramic capacitors the MIC5213 can be controlled by a CMOS or TTL compatible logic signal. When disabled, power consumption drops nearly Applications 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 Cellular telephones of the MIC5213 increases only slightly in dropout, further Laptop, notebook, and palmtop computers prolonging battery life. Key MIC5213 features include current Battery-powered equipment limiting, overtemperature shutdown, and protection against Bar code scanners reversed battery. SMPS post-regulator/dc-to-dc modules The MIC5213 is available in 2.5V, 2.6V, 2.7V, 2.8V, 3.0V, High-efficiency linear power supplies 3.3V, 3.6V, and 5.0V fixed voltages.
