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.
