XC6902
Series
-16V Input Three Terminal Negative Voltage Regulator
ETR0363-003a
■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.

CONFIGURATION
* The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking to enhance
mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the -V
IN
(No. 3) pin.
