SS8046
3.3V 2A Low-Dropout Regulator with Disable
Features
Dropout-voltage 0.5V @ I _O = 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

General Description
The SS8046 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 (V_IN < 3.3V).
Familiar regulator features such as over-temperature
and over-current protection circuits are provided to
prevent the device from being damaged by abnormal
operating conditions. A V_dis pin is provided to disable
the output when needed.
