BIPOLAR LDO REGULATOR
DUAL 1A LOW DROPOUT REGULATOR
DESCRIPTION
FEATURES
A1118 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.
Dual channel output with each individual output
can be either fixed output version or adjustable
version.
Maximum output current for each channel is 1A
Range of operation input voltage: Max. 12V
Standby current of each output: 2mA (typ.)
Line regulation: 0.1%/V (typ.)
Load regulation: 10mV (typ.)
Environment Temperature: -20°C ~85°C
Compatible with tantalum capacitor, electrolytic
capacitor and MLCC.
A1118 offers thermal shut down and current limit
functions to ensure reliability of device and power
system.
Available in PSOP8 Package
APPLICATION
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).
