DESCRIPTION

The UTC LXXLD30 is a typical LDO with the features of very

low dropout voltage as low as 0.2V 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 0.3V. 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 LXXLD30, 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 LXXLD30 can be used as an ideal to provide well supply voltage in the applications, such as

applications.
