CMOS IC

3A, ULTRA LOW DROPOUT

(0.23V@3A) LINEAR REGULATOR



DESCRIPTION

The UTC LXXLD32 is a typical LDO with the features of very low

dropout voltage as low as 0.23V at output current 3A.

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 0.5V. 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.

HSOP-8

Internally, in the UTC LXXLD32, 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 LXXLD32 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/3A) and note

book PC applications.
