DESCRIPTION
BL1118 is 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. BL1118 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).
BL1118 is available in lead (Pb)-free ESOP-8(with exposed pad for heat dissipation) package.
