DESCRIPTION  
The UTC LR78XX is a COMS positive linear regulator. One of  
it’s feature is the very low quiescent current typical as low as 4.3μA  
and its dropout voltage is extremely low with 500mA output current,  
and high ripple rejection. Each of these ICs consists of a voltage  
reference unit, an error amplifier, resistor-net for voltage setting, a  
short current limit circuit, a chip enable circuit, and so on.

These ICs perform with low dropout voltage and the chip-enable  
function. The supply current at no load of this IC is only 4.3μA, and  
the line transient response and the load transient response of the  
UTC LR78XX Series are excellent, thus these ICs are very suitable  
for the power supply for hand-held communication equipment.
