NCP1117LP
1.0 A Low-Dropout Positive
Fixed and Adjustable
Voltage Regulators
The NCP1117LP is the low power version of the popular NCP1117
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 package.
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
