LMS5214
80mA, Low Dropout Voltage Regulator with Auto
Discharge Function in SC70
General Description
The LMS5214 is a µCap, low dropout voltage regulator with
very low quiescent current, 110µA typical, at 80mA load. It
also has very low dropout voltage, typically 2mV at light load
and 300mV at 80mA.
The LMS5214 is an enhanced version of the industry stan-
dard LMS5213 with auto discharge function which actively
discharges the output voltage to ground when the device is
placed in shutdown mode. It provides up to 80mA and con-
sumes a typical of 10nA in disable mode, which helps to
extend the battery life.
The LMS5214 is optimized to work with low value, low cost
ceramic capacitors. The output typically requires only 470nF
of output capacitance for stability. The enable pin can be tied
to VIN for easy device layout.
Low ground current at full load and small package makes the
LMS5214 ideal for portable, battery powered equipment ap-
plications with small space requirements.
The LMS5214 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 2.5V, 2.6V, 2.8V, 2.9V,
3.0V and 3.3V fixed voltages. For other output voltage op-
tions, please contact National Semiconductor.
