General Description
The G9085 is a low dropout linear regulator to
provide well regulated supply for applications re-
quiring lower voltage from such as, 3.3V PC ATX
power supplies.
The G9085 provides over temperature and over
current protection circuits to prevent it from being
damaged by abnormal operating conditions.
A 100µF tantalum electrolytic capacitor is rec-
ommended at the output to improve the transient
response and stability.
Applications
PC Motherboard
Post regulation for switching DC/DC converter
High efficiency linear regulator
Battery powered instrumentation
