Product Summary
The LM431AI is a programmable shunt regulator. The output voltage can be set any value between VREF (approximately 2.5 volts) and 36 volts with two external resistors.
Parametrics
LM431AI absolute maximum ratings: (1)Cathode Voltage: 37 V; (2)Cathode Current Range (Continuous): -100 to +150 mA; (3)Reference Input Current Range: -0.05 to +10 mA; (4)Power Dissipation M, Z Suffix Package: 770 mW; (5)Power Dissipation N Suffix Package: 1000 mW; (6)Storage temperature: -65 to + 150 °C; (7)Junction Temperature: +150 °C.
Features
LM431AI features: (1)programmable output voltage to 36 volts; (2)low dynamic output impedance 0.20 Typical; (3)sink current capability of 1.0 to 100mA; (4)equivalent full-range temperature coefficient of 50ppm/°C typical; (5)temperature compensated for operation over full rated operating temperature range; (6)low output noise voltage; (7)fast turn-on response.
