Characteristic

The XC66D series consists of a voltage detector and voltage regulator

built into the one chip and is, essentially, a voltage regulator with voltage

detect capabilities.

Low power consumption and high accuracy is achieved through CMOS

and laser trimming technologies.

The detector features an output driver, hysteresis circuit, comparator and

extremely accurate standard voltage.

The regulator features an error amplification circuit, output driver with

current limiter functions, minimal input-output voltage differential and

similary accurate standard voltage.

SOT-25 (150mW) package is available.
