General Description
The G926A is a dual low dropout regulator with VOUT1
2.5V/500mA and VOUT2 3.3V/500mA, G926B is with
VOUT1 1.8V/500mA and VOUT2 3.3V/500mA. The
dropout voltage is typically 1V with 500mA load. A low
quiescent current is typical 200µA.
Familiar regulator features such as over temperature and
current limit protection circuits are provided to prevent it
from being damaged by abnormal operating conditions.
The G926 comes in a SOP-8 and SOP-8 (FD) with
power-pad package.
Applications
CD/DVD-ROM, CD/RW
Wireless LAN Card/Keyboard/Mouse
Battery-Powered Equipment
XDSL Router
