HIGH DRIVER REGULATOR

DESCRIPTION
The UTC UT7500 series is a low voltage regulator implemented
by CMOS technology which is composed of a three-terminal high
current. The input voltage for it is allowed as high as 24V and the
output voltage are fixed at 1.8V、3.0V、3.3V、3.6V、4.0V and 5.0V.
Besides, it delivers 100mA output current. Other outstanding
features of UTC UT7500 include low voltage drop and low quiescent
current.
When being used with external components, UTC UT7500 can
obtain variable voltages and currents.
UTC UT7500 series is very suitable for applications, such as
battery-powered equipment, communication equipment and
audio/video equipment.
