1A Bipolar Linear Regulator
LESHAN RADIO COMPANY, LTD.
LR1117'
DESCRIPTION
LR1117 is a series of low dropout three- terminal
regulators with a dropout of 1.3V at 1A load current.
LR1117 features a very low standby current 2mA
compared to 5mA of competitor.
Other than a fixed version, Vout = 1.2V, 1.8V, 2.5V,
2.85V, 3.3V, 5V, LR1117 has an adjustable version,
which can provide an output voltage from 1.2ϱsto
ϭϮV with only two external resistors.
LR1117 offers thermal shut down functions, to
assure the stability of chip and power system. And
it uses trimming technique to guarantee output
voltage accuracy within r2%. Other output voltage
accuracy can be customized on demand, such as
r1%
LR1117 is available in SOT-223, TO-252 power
package.
