WT1117A
General Description:
WT1117A of positive adjustable and fixed regulators is designed to provide 1.0A output with
low dropout voltage performance. On-chip trimming adjusts the reference voltage to 1.5%.
For usage on working in post regulators or microprocessor power supplies, low voltage
operation and fast transient response are required.
WT1117A is available in surface-mount SOT-223 and TO-252 packages.
Features:
* Adjustable or Fixed Output
* Output Current of 1.0A
* Dropout Voltage(Typical) 1.15V @1.0A
* Line Regulation 0.2% max.
* Load Regulation 0.4% max.
* Fast Transient Response
* Current Limit Protection
* Thermal Shutdown Protection
Applications:
* High Efficiency Linear Regulators
* Post Regulators for Switching Supplies
* Microprocessor Supply
* Hard Drive Controllers
* Battery Chargers
* Adjustable Power Supply
