family of low dropout voltage regulators, with reduced quiescent
current. It is intended primarily for high volume consumer
applications over the 0 to 125 degree temperature range. Capable of
providing an output current in excess of 1 A, with a dropout voltage of
1.3 V at 1 A full current load, the series consists of an adjustable and
five fixed voltage versions of 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V.
Internal protection features consist of output current limiting and
built ? in thermal shutdown. The NCP1117LP series can operate up to
18 V max input voltage. The device is available in the popular
SOT ? 223 and DPAK packages.
Features
? Output Current in Excess of 1.0 A
? 1.4 V Maximum Dropout Voltage at 1 A
? Quiescent Current over 10 times Lower than Traditional 1117
? Fixed Output Voltages of 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V
? Adjustable Output Voltage Option
? No Minimum Load Requirement for Fixed Voltage Output Devices
? Good Noise Rejection
? Current Limit and Thermal Shutdown Protection
? Operation up to 18 V Input
? These are Pb ? Free Devices
Applications
? TV and Monitors
? Set Top Boxes and Entertainment Devices
? Switching Power Supply Post Regulation
? Game Consoles and Consumer Applications
? Hard Drive Controllers
