General Description
The SR6251P series is a group of positive voltage output, three-pin regulators that provide a high
current even when the input/output voltage differential is small. Low power consumption and high accuracy
is achieved through CMOS and laser trimming technologies. The SR6251P consists of a high-precision
voltage reference, an error amplification circuit, and a current limited output driver. Transient response to a
load variations have improved in comparison to the existing series.SOT-89 packages are available..
