28V Operation Voltage Regulator with Voltage Detector

●Supply Current vs. Input Voltage

■GENERAL DESCRIPTION

The XC6408 series is a positive voltage regulator IC manufactured using CMOS process with 28V operation voltage. The series

consists of a voltage reference, an error amplifier, a current limiter, a thermal shutdown circuit and a phase compensation circuit

plus a driver transistor. The output voltage and the detect voltage are user selectable in 0.1V increments. The over current

protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current

reaches current limit level or the junction temperature reaches temperature limit level. The XC6408D series monitors its output

voltage and provides reset signal if its output voltage falls below the pre-set voltage. This reset time (release delay time) can be

set by an external capacitor. The XC6408E series monitors an external power supply and enables the output to be turned off

and the IC becomes a stand-by mode.
