DESCRIPTION
LC1118is a dual channel low-dropout regulator that
delivers a maximum current of 1A for each
individual output. Typical dropout voltage at 1A
load current is 1.3V. Each individual output voltage
can be set independently as fixed voltage (e.g 1.2V,
1.8V, 2.5V, 3.3V, 5V) or adjustable output which can
provide an output voltage from 1.25 to 12V with
two external resistors. The output accuracy of each
channel is set within 2% by trimming.
LC1118 offers thermal shut down and current limit
functions to ensure reliability of device and power
system.
Package input/output pin configuration can be
customized on demand ( i.e both output can share
one input to save one input capacitor and
corresponding PCB real estate).

LC1118is available in lead (Pb)-free ESOP-8(with
exposed pad for heat dissipation) package.
