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 quies-
cent current is smaller when the regulator is in the
dropout mode (V_IN < 12V).
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.
