General Description
The G9105 positive 5V voltage regulator features the
ability to source 1A of output current. The dropout
voltage is 0.5V at 1A 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
< 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 V
EN
pin is pro-
vided to disable the output when needed.
