150mA CMOS LDO WITH

SHUTDOWN AND REFERENCE

BYPASS



DESCRIPTION

The UTC LR1185 is a 150 mA LDO regulator has very high

PSRR and super low dropout voltage especially suitable for

wireless and portable applications.

In the field of hand-held wireless devices, board space and

battery life are the main concerns of designers and end-users.

Because of the low quiescent current and low ESR ceramic

capacitors, UTC LR1185 can satisfy those concerns.

Furthermore, low current consumption (50μA), high output

accuracy, current limiting protection, and high ripple rejection ratio

are advantages of UTC LR1185.



FEATURES

* Operating voltage ranges : 2.7V~5.5V

* Dropout : 100mV at 150mA

* When IC shutdown: 5mA discharge current of VOUT

* Extreme low Noise for DSC application

* Extreme fast response in line/load transient

* Internal current limiting protection

* Internal thermal shutdown protection

* High PSRR

* Recommended 1μF output capacitor only for stability

* With TTL logic controlled shutdown input
