G9308A
8V 3A Low Dropout Regulator with Disable
Features
General Description
Dropout voltage 0.85V @ IO = 3A
Dropout voltage 0.2V @ IO = 0.5A
Output current in excess of 3A
Output voltage accuracy ±2.5%
Quiescent current, typically 1.2mA
Internal short circuit current limit
Internal over temperature protection
TO-220 4pin Full-mold package
ON/OFF control
The G9308A positive 8V voltage regulator features the
ability to source 3A of output current. The dropout
voltage is 0.85V at 3A output current. The typical qui-
escent current is 1.2mA. Furthermore, the quiescent
current is smaller when the regulator is in the dropout
mode (VIN < 8V).
Familiar regulator features such as over tem-
perature and over current protection circuits are
provided to prevent it from being damaged by
abnormal operating conditions. Pin Vdis is pro-
vided to disable the output when needed.
