nju7757/58 -1- ver.2006-02-23 low dropout voltage regulator general discription package outline nju7757/58 is a low dropout voltage regulator with on/off control. advanced cmos technology achieves low quiescent current. sc-82ab package and 0.1uf small output capacitor make the nju7757/58 suitable for space conscious applications. NJU7758 features shunt switch which improves turn off response of output voltage when on/off control is used. features pin configuration low quiescent current iq=20 a typ.(i o =0ma) output capacitor with 0.1uf ceramic capacitor output current i o (max.)=100ma high precision output v o 1.0% low dropout voltage 0.15v typ.
