G940/G941
3.7V 400mA Low Dropout Regulator
Features
General Description
ꢀDropout voltage typically 0.8V @ IO = 400mA
ꢀOutput current in excess of 400mA
ꢀOutput voltage accuracy +3%/-2%
ꢀQuiescent current, typically 600µA
ꢀInternal short circuit current limit
ꢀInternal over temperature protection
The G940/G941 positive 3.7V voltage regulator fea-
tures the ability to source 400mA of output current
with a dropout voltage of typically 0.8V over the en-
tire operating temperature range. A low quiescent
current is provided over the entire output current
range. The typical quiescent current is 0.6mA. Fur-
thermore, the quiescent current is smaller when the
regulator is in the dropout mode (VIN < 3.7V).
Familiar regulator features such as over temperature
and over current protection circuits are provided to
prevent it from being damaged by abnormal operating
conditions.
