General Description
The G9184 is a high performance positive voltage
regulator designed for use in applications requiring
very low Input voltage and low dropout voltage. It op-
erates with a VIN as low as 1.5V with output voltage
1.2V. The supply current is 80µA. The G9184 features
low dropout, ideal for applications where VOUT is very
close to VIN. The over-current protection limit is set at
550mA typical. An overtemperature protection circuit is
built-in in the G9184 to prevent thermal overload. Ad-
ditionally, the G9184 has an enable pin to further re-
duce power dissipation while shutdown. In the shut-
down mode, the maximum supply current is less than
1µA. The G9184 provides excellent regulation over
variations in line, load and temperature.
The G9184 is available in the power SOT-89,
SOT-223, SOT-23-5 and ADFN1.5X1.5-6 package. It
is available from 0.8V to 1.8V, 0.05V increments, in-
ternally preset outputs.
