G9233
3.3V 2A Low Dropout Regulator with Disable
Features
Dropout voltage 0.5V @ IO = 2A
Output current in excess of 2A
Output voltage accuracy ±2.5%
Quiescent current, typically 5mA
Internal short circuit current limit
Internal over temperature protection
TO220 4pin Full-Mold package
ON/OFF control
General Description
The G9233 positive 3.3V voltage regulator features
the ability to source 2A of output current. The dropout
voltage is 0.5V at 2A output current. The typical qui-
escent current is 5mA. Furthermore, the quiescent
current is smaller when the regulator is in the dropout
mode (VIN < 3.3V).
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. A Vdis pin is pro-
vided to disable the output when needed.
