General Description
The G9183 is a high performance positive voltage
regulator designed for use in applications requiring
very low Input voltage and very low dropout voltage at
up to 300mA. It operates with a VIN as low as 1.25V
and VBIAS voltage 3V with output voltage programma-
ble as low as 0.8V. The G9183 features ultra low
dropout, ideal for applications where VOUT is very close
to VIN. Additionally, the G9183 has an enable pin to
further reduce power dissipation while shutdown. The
G9183 provides excellent regulation over variations in
line, load and temperature. The G9183 provides a
power OK signal to indicate if the voltage level of VO
reaches 92% of its rating value.
The G9183 is available in the power TSOT-23-6,
SOT-23-6 and SOP-8 package. It is available with
0.9V, 1.0V, 1.1V, 1.2V, 1.5V, 1.6V, 1.7V and 1.8V in-
ternally preset outputs that are also adjustable using
external resistors.
