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_IN for easy device layout.
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.
