Preliminary

CMOS IC

1.5A LDO REGULATOR



DESCRIPTION

The UTC UR1171 is a typical LDO (linear regulator) with the

features of high output voltage accuracy, low supply current, low

ON-resistance, and high ripple rejection.

During operation of the UTC UR1171, the dropout voltage is

very low and the response of line transient and load transient are

very well.

Internally, there’re many functions of UTC UR1171 which can

be seen in the block figure. There are a voltage reference unit, an

error amplifier, resistor-net for voltage setting, a current limit circuit,

and a chip enable circuit in each UTC UR1171.

SOP-8

The UTC UR1171 can be used as an ideal of the power supply

for hand-held communication equipment, such as: power source for

portable communication equipment, power source for electrical

appliances, for example, cameras, VCRs and camcorders and

power source for battery-powered equipment.



FEATURES

* Low standby current (TYP=0.1µA)

* Supply current (TYP=80µA)

* Output current (MIN=1.5A@V_IN=V_OUT+1.0V)

* Output voltage accuracy (±2.0%)

* Output voltage (1.2V~5.0V)

* Low dropout voltage (TYP=0.09V@V_OUT=3.0V, I_OUT=300mA)

* Line regulation (TYP=0.05%/V)

* Low temperature-drift coefficient of output voltage

* Built-in thermal shunt circuit

* Built-in current limit circuit
