SSP7901
Current 300mA High Voltage 40V Low Power LDO
SSP7901
General Description
The SSP7901 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 SSP7901consists of a high-precision voltage reference, an error amplification circuit, and a
current limited output driver. Transient response to load variations have improved in comparison to
the existing series.
