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.
