General Description
even when the input/output voltage differential is small. Low power consumption and high accuracy is
achieved
through CMOS and laser trimming technologies.
The SSP7603 consists 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.
SOT89-3,SOT23-3
and SOT23-5 packages are available.
