G9338
Ultra Low Output Voltage Linear N-FET Controller
Features
General Description
0.5V±2% Reference Voltage
The G9338 series are ultra low output voltage linear
N-FET controllers designed to simplify power manage-
ment for notebook computers. Both voltage adjustable
(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.
Adjustable Output Voltage Down to 0.5V
MLCC and POSCAP Stable
Enable Control
Power Good Signal Output
Under Voltage Short Circuit Protection
Drive N-Channel MOSFETs
Output Voltage Discharge (G9338-XXX)
SOT-23-6 Package
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.
Applications
Notebook or Desknote Computers
