CMOS IC  
THREE-TERMINAL LOW POWER  
VOLTAGE REGULATORS  
„
DESCRIPTION  
The UTC UT71XX series is a set of three- Terminal low power  
voltage regulators implemented in CMOS technology. They are  
available with several fixed output voltages ranging from 1.5V~7.0V.  
The advantage of CMOS technology is low voltage dropout and low  
quiescent current.  
Although designed primarily as fixed voltage regulators, these  
devices can be used with external components to obtain variable  
voltages and currents.  
„
FEATURES  
* Accurate output voltage range (±2.4%)  
* Low power consumption  
* Low voltage dropout  
* Low temperature coefficient  
* Wide operating voltage (24V Max.)
