Overview
XC6902 Series -16V Input Three Terminal Negative Voltage Regulator ETR03063-004b ■GENERAL DESCRIPTION The XC6902 Series is a negative voltage CMOS regulator which includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators.
XC6902 is a 3 terminal negative voltage regulator (without CE pin) which is capable of accepting -16V input.
The over current protection circuit will operate when the output current reaches limit current.
The thermal shutdown circuit will operate when the junction temperature reaches limit temperature.
