LM2595 - 1A Step-Down Voltage Regulator

Download the LM2595 datasheet PDF. This datasheet also covers the LM2 variant, as both devices belong to the same 1a step-down voltage regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM2595 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.

Key Features

  • include a guaranteed ± 4% tolerance on output voltage under specified input voltage and output load conditions, and ± 15% on the oscillator frequency. External shutdown is included, featuring typically 85 µA stand-by current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions. Features n 3.3V, 5V, 12V, and adjustable output versions n Adjustable version output voltage.

LM2595 SIMPLE SWITCHER Power Converter 150 kHz 1A Step-Down Voltage Regulator May 1999 LM2595 SIMPLE SWITCHER ® Power Converter 150 kHz 1A Step-Down Voltage Regulator General Description The LM2595 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, and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation†, and a fixed-frequency oscillator.
