Bay Linear

Inspire the Linear Power

1.0A Step Down Switching voltage Regulator

Adjustable & Fix Output

LM2575

Description

The Bay Linear LM2575 contains fixed and adjustable

switching voltage regulators that require a minimum of

external components. All circuitry necessary to build a

buck-switching regulator is included.

The LM2575 is available in 3.3V; 5V, 12V & 15V fixed

voltages, or an adjustable version with an output voltage

range from 1.23V to 37V. The guaranteed accuracy for

specified input and load conditions is

±4%.

The LM2575 can supply 1A with an excellent load and

line regulation. Protection such as cycle-by-cycle

current limiting or thermal shutdown has been designed.

In standby mode, the current consumption has been

minimized (200µA).

For 3A step-down switching regulators refer to LM2576
