Product Overview
SOT-23-3 (MP003-C)
HSNT-8(1616)B (PY008-B)Maximum shunt current : 15 mA (S-19760) ｜ 30 mA (S-19761)
This IC is high-precision, low temperature coefficient, and low output noise shunt voltage reference developed using CMOS process technologies and is available in SOT-23-3 and compact HSNT-8(1616)B packages. Power can also be supplied from a high input voltage by selecting an appropriate external shunt resistor, making it possible to generate high-precision system reference voltage. The output voltage (reverse breakdown voltage) can be selected from 6 internally fixed voltages of 2.048 V, 2.5 V, 3.0 V, 3.3 V, 4.096 V, or 5.0 V.
This IC is available in 3 accuracy types. A type has an output voltage accuracy of ±0.1% and output voltage temperature coefficient of 20 ppm/°C max. (Ta = -40°C to +125°C).
The IC is compatible with a wide range of shunt currents with a maximum shunt current of 30 mA.
