Preliminary
1.5A CMOS LDO
CMOS IC
„ DESCRIPTION
The UTC L11815A is a COMS linear regulator. One of it’s
feature is very low quiescent current typical as low as 45μA
and its dropout voltage is extremely low with 1.5A output
current.
The internal circuit includes thermal shutdown and current
fold-back mechanism to prevent device failure when the circuit
is operated in the bad conditions.
In application, the UTC L11815A needs a low noise,
regulated supply. For stable operation, the output capacitance
value should be 4.7μF or more.
The UTC L11815A is an ideal for battery applications,
such as instrumentations, portable electronics, wireless
devices, PC peripherals, and battery powered widgets. The
output voltage values are set during manufacturing and the
accuracy is tighten 1.5%.
