General Description
The G9218 positive 1.8V voltage regulator features
the ability to source 2A of output current. The dropout
voltage is 0.7V at 2A output current. The typical qui-
escent current is 1.8mA. Furthermore, the quiescent
current is smaller when the regulator is in the dropout
mode.
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.
