XC66D Series
Positive Voltage Regulator with built-in Voltage Detect Functions
DETAILS
General Description
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, com-
parator and extremely accurate standard voltage.
The regulator features an error correction circuit, output driver
with current limiter functions, minimal input-output voltage
differential and similarly accurate standard voltage.
SOT-25 ( 150mW) package available.
