LM2574N-12/NOPB TI Voltage Regulators - DC DC Switching Regulators

The LM2574 is a SIMPLE SWITCHER® step-down regulator delivering up to 500-mA output current with a fixed 12-V output, operating from an 8-V to 40-V input. It features a 52-kHz fixed switching frequency and requires only 4 external components. The device includes thermal shutdown, current limiting, and an on/off control pin, with efficiency up to 80% typical. Packaged in an 8-pin PDIP (N) for through-hole mounting, it is standard for easy-to-use step-down regulation. Applications include 24-V to 12-V conversion in industrial controls and automotive electronics. In stock at HL Electronics – request a quote for fast delivery.
