General Description
The H7651 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 H7651 consists of a high-precision voltage
reference, an error amplification circuit, and a
current limited output driver. Transient response
