Preliminary
800MA LDO REGULATOR
CMOS IC
DESCRIPTION
The U TC UR1 170 is a t ypical LDO (li near regul ator) with the
features of hig h output voltage accurac y, lo w supply curr ent, lo w
ON-resistance, and high ripple rejection.
During op eration of the UT C UR1170, th e drop out vo ltage i s
very l ow an d the resp onse o f line transi ent and lo ad tran sient ar e
very well.
Internally, ther e’re man y fun ctions of UT C UR1170 w hich can
be seen in the block figur e. There are a volt age reference unit, an
error amplifier, resistor-net for voltage setting, a current limit circuit,
and a chip enable circuit in each UTC UR1170.
The UTC UR1170 can be us ed as an id eal of the po wer supply
for hand-held communication equipment, such as: power source for
portable com munication equipment, po wer source f or electrica l
appliances, fo r exampl e, ca meras, VCRs and c amcorders an d
power source for battery-powered equipment.
FEATURES

of 1.2V~4.0V)
* Output current (MIN=800mA@VIN=VOUT+1.0V)
* Low dropout voltage
* Line regulation
* High output voltage accuracy
* Low temperature-drift coefficient of output voltage
* Built-in thermal shunt circuit
* Built-in current limit circuit
