SE1085

3A Low Dropout Positive

Adjustable or Fixed-Mode Regulator

Description

The SE108

5 is a low dropout at positive adjustable or fixed-mode

regulator with min. of

3A output current capability. The product is

specifically designed to provide well-regulated supply for low voltage

IC applications such as high-speed bus termination and low current

3.3V logic supply. SE108

5 is also well suited for other applications

such as VGA cards. SE108

5 is guaranteed to have lower than 1.4V

dropout at full load current making it ideal to provide well regulated

outputs of 1.25 to

5V with 4.7 to 12V input supply.

* 3-Terminal Adjustable or Fixed 1.5V,1.8V,2.5V,3.3V,5.0V

Features

*

1.4V Max. Dropout Full Load Current

* Output Current Limiting

* Fast Transient Response

* Built-in Thermal Shutdown
