1A Bipolar Linear Regulator
LESHAN RADIO COMPANY, LTD.
LR1117C
DESCRIPTION
LR1117C is a series of low dropout thre-e terminal
regulators with a dropout of 1.3V at 1A load current.
LR1117C features a very low standby current 2mA
compared to 5mA of competitor.
Other than a fixed version, Vout = 1.2V, 1.5V, 1.8V,
2.5V, 3.3V, 5V, and 12V, LR1117C has an adjustable
version, which can provide an output voltage from
1.25 to 12V with only two external resistors.
LR1117C offers thermal shut down and current limit
functions, to assure the stability of chip and power
system. And it uses trimming technique to
guarantee output voltage accuracy within 2%.
Other output voltage accuracy can be customized
on demand, such as 1%
LR1117C is available in SOT-223,TO-252 power
package.
FEATURES
Other than a fixed version and an adjustable
version, output value can be customized on
demand.
Maximum output current is 1A
Range of operation input voltage: Max 12V
Standby current: 2mA (typ.)
Line regulation: 0.1%/V (typ.)
Load regulation: 10mV (typ.)
