LM2574MX-5.0/NOPB

Manufacturer: Texas Instruments

Description:
The LM2574MX-5.0/NOPB is a step-down voltage regulator that provides all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5A load with excellent line and load regulation. It requires a minimum number of external components, it is simple to use and include internal frequency compensation and a fixed-frequency oscillator. This product offers a high-efficiency replacement for popular three-terminal linear regulators, because of its high efficiency, the copper traces on the printed-circuit board (PCB) are normally the only heat sinking needed. Features Requires only four external components TTL shutdown capability, low power standby mode High efficiency Uses readily available standard inductors 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)
