500mA, LOW DROPOUT, LOW

NOISE ULTRA-FAST WITH SOFT

START CMOS LDO REGULATOR

DESCRIPTION

UTC LR1120, a 500mA 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 LR1120 can satisfy those concerns.

Furthermore, low current consumption in shutdown mode

(0.7μA), fast turn-on time (<70μs), high output accuracy, current

limiting protection, and high ripple rejection ratio are advantages of

UTC LR1120.

FEATURES

* Operating Voltage Ranges : 2.2V to 5.5V

* Dropout : 250mV at 500mA

* 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
