2575T-12 Datasheet (National Semiconductor)

2575T-12, LM2575

The LM2575 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation.

These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and a

2575T-12 Features

* include a guaranteed ± 4% tolerance on output voltage within specified input voltages and output load conditions, and ± 10% on the oscillator frequency. External shutdown is included, featuring 50 µA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as th
