Global Mixed-mode Technology Inc.
G9225
2.5V 2A Low Dropout Regulator with Disable
Features
General Description
Dropout voltage 0.5V @ IO = 2A
Output current in excess of 2A
Output voltage accuracy ±2.5%
The G9225 positive 2.5V 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 2.5mA. Furthermore, the quiescent
current is smaller when the regulator is in the dropout
mode.
Quiescent current, typically 2.5mA
Internal short circuit current limit
Internal over temperature protection
TO-220 4pin Full-Mold package
ON/OFF control
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 VEN pin is pro-
vided to disable the output when needed.
