The LM2574MX-ADJ/NOPB is a SIMPLE SWITCHER® step-down Voltage Regulator for use with on-card switching regulators. The LM2574xx series of regulator is monolithic integrated circuit 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. This device is available in fixed output voltages of 3.3, 5, 12, 15V and an adjustable output version. Requiring a minimum number of external components, this regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2574xx series 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. A standard series of inductors optimized for use with the LM2574 are available from several different manufacturers.
● Requires only 4 external components
● TTL shutdown capability and low-power standby mode
● High efficiency
● Uses readily available standard inductors
● Thermal shutdown and current-limit protection
● Green product and no Sb/Br
