Global Mixed-mode Technology Inc.
12V 1A Low Dropout Regulator
Features
General Description
„
The G78D12A positive 12V voltage regulator features
the ability to source 1A of output current. The dropout
voltage is 0.5V at 0.5A output current. The typical
quiescent current is 1.2mA. Furthermore, the quiescent current is smaller when the regulator is in the
dropout mode (VIN < 12V).
