LINEAR INTEGRATED CIRCUIT
ALTERNATOR VOLTAGE
REGULATOR
DESCRIPTION
The UTC UAC3092A is designed for Load Response Control
and voltage regulation of diode rectified alternator charging
systems for automotive applications.
FEATURES
* Forced load response control (LRC) with heavy load transitions
at low RPM
* Voltage regulated to ± 0.1V @ 25°C
* External resistor adjustable operating frequency
* Regulation is effective with loads as high as 1.0A
* Load dump protection of lamp, field control devices, and loads
* Undervoltage, overvoltage , phase fault (broken belt) detection
and duty cycle limited protections
SOP -20
*Pb-free plating product number: UAC3092AL
