Key benefits
} Simple solution to achive a stabilized voltage
} Any output voltage from 2.5 to 36 V can be set
by just two external resistors
} Full temperature range from -40 to 125 °C
} Low temperature drift: typically 6 mV
(between 0 and 70 °C)
} Low output noise
} High quality level according AEC-Q100
Key applications
} Shunt voltage regulator
} Precision current limiter
} Precision constant current sink
} Isolated feedback loop for Switch Mode Power
Supply (SMPS)
