Global Mixed-mode Technology Inc.
G9205
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%
Quiescent current, typically 5mA
Internal short circuit current limit
Internal over temperature protection
TO-220 4pin Full-Mold package
ON/OFF control
The G9205 positive 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 5mA. Furthermore, the quiescent
current is smaller when the regulator is in the dropout
mode (VIN < 5.5V).
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.
