Programmable Shunt Regulator
Features Description •
•
•
• The FAN431A is a three-terminal output adjustable regulator with thermal stability over the full operating temperature range. The output voltage can be set to any value
between VREF (approximately 2.5 V) and 36 V with two
external resistors. This device has a typical dynamic output impedance of 0.2 . Active output circuit provides a
sharp turn-on characteristic, making this device excellent
replacements for zener diodes in many applications. Programmable Output Voltage to 36 V
Low Dynamic Output Impedance: 0.2 (Typical)
Sink Current Capability: 1.0 to 100 mA
Equivalent Full-Range Temperature Coefficient of
50 ppm/°C (Typical)
• Temperature Compensated for Operation Over Full
Rated Operating Temperature Range
• Low Output Noise Voltage
• Fast Turn-on Response TO-92 1 1. Ref 2. Anode 3. Cathode Ordering Information …
