B4251 Product details

Description

The B4251 series are a group of positive output voltage, five-pin regulators, which provide a high current even when the input/output voltage differential is small.

Features

include a Shutdown Pin that reduces supply current to 0.5µA max and a 470pF Bypass input to ground reduces noise present on the internal reference, which in turn significantly reduce output noise. If output noise is not concern, this input maybe left unconnected. Larger capacitor values cap be used, but results in longer time period to rated output voltage when power initially applied. The ON/OFF pin enables the output to be turned off, resulting in reduced power consumption. Provided in SOT-25.
