LT1185 Low Dropout Regulator FEATURES ■ Low Resistance Pass Transistor: 0.25Ω ■ Dropout Voltage: 0.75V at 3A ■ ±1% Reference Voltage ■ Accurate Programmable Current Limit ■ Shutdown Capability ■ Internal Reference Available ■ Full Remote Sense ■ Low Quiescent Current: 2.5mA ■ Good High Frequency Ripple Rejection ■ Available in 5-Lead TO-220 and DD Packages DESCRIPTIO The LT®1185 is a 3A low dropout regulator with adjustable current limit and remote sense capability. It can be used as a positive output regulator with floating input or as a standard negative regulator with grounded input. The output voltage range is 2.5V to 25V, with ±1% accuracy on the internal reference voltage. The LT1185 uses a saturation-limited NPN transistor as the pass element.
