LMS5213
80mA, 碌Cap, Low Dropout Voltage Regulator in SC70
General Description
The LMS5213 is a 碌Cap, low dropout voltage regulator with
very low quiescent current, 220碌A(chǔ) 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 1碌A(chǔ) in disable mode.
The LMS5213 is optimized to work with low value, low cost
ceramic capacitors. The output typically require only 0.47碌F
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 鈭?0藲C to +125藲C
temperature range and is available in 2.8V fixed voltage. For
other output voltage options, please contact National Semi-
conductor.
