3A, ULTRA LOW DROPOUT (0.
23V@3A) LINEAR REGULATOR
CMOS IC
DESCRIPTION
The UTC L1806 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.
Internally, in the UTC L1806, there’re many functions which can be seen in the block figure to prevent the IC from...
