XC66D SeriesꢀPositive Voltage Regulator with built-in Voltage Detect Functions
DETAILS
General Description
Features
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.
Maximum Output Current:
100mA(Within the max. continuous total power dissipation,
VOUT=5.0V)
Low power consumption and high accuracy is achieved
through CMOS and laser trimming technologies.
Output Voltage Range:
2.0V to 6.0V programmable in 0.1V steps ( Standard 5.0V )
Highly Accurate Output Voltage: Set-up voltage accuracy ± 2%
Output Voltage Temp.Characteristics:TYP ± 100ppm/°C
Detect Voltage Range: 1.8V to 6.0V programmable in 0.1V steps
Highly Accurate Detect Voltage: Set-up voltage accuracy ± 2%
Low Power Consumption:TYP 3.2µA (VOUT = 5.0V)
Detect Voltage Temp.Characteristics:TYP ± 100ppm/°C
Detect Voltage Output Configuration: N-ch open drain
CMOS ( High level = VOUT )
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.
Line Regulation:TYP 0.1 %/V
Ultra Small Package: SOT-25 (150mW) mini-mold
