RS421/ RS422 RS421/ RS422 Precision Programmable Reference FEATURES DESCRIPTION • Reference Voltage Tolerance at 25°C 0.5% • Programmable output voltage to 36V • Low dynamic output impedance 0.1Ω • Sink current capability of 0.5mA to 100mA • Equivalent full-range temperature coefficient of 50ppm/°C typical • Temperature compensated for operation over full rated operating temperature range • Low output noise voltage • Fast turn on response • Operation junction temperature from -40°C to 150°C • The RS421 and RS422 device are three-terminal adjustable shunt regulators, with a guaranteed thermal stability over applicable temperature ranges. The output voltage can be set to any value between V REF (approximately 1.18V) and 36V with two external resistors. These devices have provided a very sharp turn-on characteristic, making these devices excellent replacement for Zener diodes in many applications. Both the RS421 and RS422 devices are offered in two grades, with initial tolerances (at 25°C) of 0.5%.
