General Description
The G9338 series are ultra low output voltage linear
N-FET controllers designed to simplify power man-
agement for notebook computers. Both voltage ad-
justable (G9338-ADJ) version and voltage fixed
(G9338-XXX) version are available for SOT23-6
package. The output voltage can be adjusted from
0.5V to 2.5V for G9338-ADJ. And there are four fixed
voltage (1.05V, 1.35V, 1.5V, 1.8V) available for
G9338-XXX.
Both versions feature a 0.5V reference voltage with
±2% accuracy providing tight regulation of the output
voltage, enable control, open drain power good signal,
under-voltage protection and soft start. The G9338-
XXX features additional output voltage discharge func-
tion during shutdown.
