LC1117 1A Bipolar Linear Regulator DESCRIPTION FEATURES Other than a fixed version and an adjustable LC1117 is a series of low dropout three-terminal version, output value can be customized on regulators with a dropout of 1.3V at 1A load current. demand. LC1117 features a low standby current 2mA. Maximum output current is 1A Range of operation input voltage: Max 18V Other than a fixed version (Vout = 1.2V, 1.5V, 1.8V, Standby current: 2mA (typ.) 2.5V, 3.3V, 5V, and 12V), LC1117 has an adjustable Line regulation: 0.1%/V (typ.) version, which can provide an output voltage from Load regulation: 10mV (typ.) 1.25 to 12V with only two external resistors. Environment Temperature: -40C~85 C Compatible with tantalum capacitor, LC1117 offers thermal shut down and current limit electrolytic capacitor and MLCC. functions, to assure stability of chip and power system. Trimming technique is used to guarantee output voltage accuracy within 2%. Other output APPLICATIONS voltage accuracy such as 1% can be customized on demand.
