Voltage Regulator, LM2575SX-12/NOPB, Texas Instruments
The LM2575SX-12/NOPB regulator is a monolithic integrated circuit that provides all the active function for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. Requiring a minimum number of external component, this regulator is simple to use and includes internal frequency compensation and a fixed-frequency oscillator. The LM2575SX-12/NOPB offers a high-efficiency replacement for a popular three-terminal linear regulator. It substantially reduces the size of the heat sink, and in many cases no heat sink is required.
Features
- Specified 1A Output Current
- Requires Only 4 External Components
- TTL shutdown capability, low-power standby mode
- High efficiency
- Thermal shutdown and current-limit protection
Applications
- Simple high-efficiency step-down (buck) regulator
- Efficient preregulator for linear regulators
- On-card switching regulators
- Positive-to-negative converter (buck-boost)
