LMS5213

80mA, µCap, Low Dropout Voltage Regulator in SC70

General Description

•

The LMS5213 is a µCap, low dropout voltage regulator

with very low quiescent current, 220µA typical, at 80mA

load. It also has very low dropout voltage, typically 20mV

at light load and 330mV at 80mA.

The LMS5213 provides up to 80mA and consumes a typical

of 1µA in disable mode.

The LMS5213 is optimized to work with low value, low cost

ceramic capacitors. The output typically require only 0.47µF

of output capacitance for stability. The enable pin can be tied

to V

The LMS5213 is designed for portable, battery powered

equipment applications with small space requirements.

The LMS5213 is available in a space saving 5-pin SC70

package. Performance is specified for the −40˚C to +125˚C

temperature range and is available in 2.8V, 3.0V and 3.3V

fixed voltages. For other output voltage options, please con-

tact National Semiconductor.
