Preliminary

CMOS IC

0.8V REFERENCE ULTRA LOW

DROPOUT LINEAR REGULATOR



DESCRIPTION

The UTC LXXLD20 is a typical LDO with the features of very low

dropout voltage as low as 0.1V at output current 2A.

For normal operation, two supply voltages are necessary. One called

control voltage from other equipment can shutdown the output voltage and

it should pull and hold the voltage of EN pin less than 0.3V. Another one is

the main supply voltage whose purpose is for main power conversion, to

keep the power dissipation low, and to make the dropout voltage lower.

Internally, in the UTC LXXLD20, there’re many functions which can be

seen in the block figure to prevent the IC from being damaged. Internal

Power-On-Reset (POR) circuit can control the two supply voltages to

prevent fault operations of the circuit; the thermal shutdown circuit is able

to protect the device from over thermal operation, and a current limit

function will keep the device work safely under current over-loads.

The UTC LXXLD20 can be used as an ideal to provide well supply

voltage in the applications, such as front-side-bus termination on

motherboard, NB applications, front side bus V_TT(1.2V/2A) and note book

PC applications.
