Overview
UNISONIC TECHNOLOGIES CO.
, LTD UR1170 Preliminary CMOS IC 800MA LDO REGULATOR  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 * Low standby current * Ultra-Low supply current * Output voltage (stepwise setting with a step of 0.
1V in the range 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  ORDERING INFORMATION Ordering Number Lead Free UR1170xL-S08-T UR1170xL-S08-R UR1170xL-S08-R Halogen Free UR1170xG-S08-T UR1170xG-S08-R Package Packing SOP-8 SOP-8 Tube Tape Reel (1)Packing Type (2)Package Type (3)Lead Free (4)Enable Threshold Level (1) T: Tube, R: Tape Reel (2) S08: SOP-8 (3) L: Lead Free, G: Halogen Free (4) L: Low, H: High www.
