Very low quiescent current (20 μA typ. at no load, 0.03 μA typ in off mode)
Output voltage tolerance:±0.5 % (A version) or ± 2.0 % @ 25 °C (standard version)
200 mA guaranteed output current
High PSRR (80 dB@1 kHz, 50 db@100 kHz)
Wide range of output voltages available on request:from 0.8 V up to 5.0 V in 50 mV step
Logic-controlled electronic shutdown
Internal soft-start
Optional output voltage discharge feature
Compatible with ceramic capacitor COUT = 0.47 μF
