1 / 7 page Page No. : 1/7 AVANTICS - AX431 Series Specification No.: 050308-FE0001 AX431 Series Adjustable Shunt Regulator Description The AX431 series are three-terminal adjustable regulators with guarante- ed thermal stability over applicable temperature ranges. The output voltage may be set to any value between V REF (approximately 2.495 volts) and 36 volts with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacement for zener diodes in many applications. Features • Programmable output voltage • Temperature coefficient is 50ppm/oC typical • Temperature compensated for operation over full temperature range • Low output noise voltage • Fast turn on response Ordering Information Package V REF: 2.495 ±2% V REF: 2.495 ±1% V REF: 2.495 ±0.5% SOT-23 AX431AN AX431BN AX431CN SOT-89 AX431AM AX431BM AX431CM TO-92 AX431AA AX431BA AX431CA SO-8 AX431AS AX431BS AX431CS Absolute Maximum Ratings (Operating temperature range applies unless otherwise specified) Characteristics Symbol Value Unit Cathode Voltage V KA 36 V Cathode Current Range (Continuous) I K -100~+150 mA Reference Input Current Range I REF 0.05~+10 mA SOT-23 280 SOT-89 770 TO-92 770 Power Dissipation P D SO-8 770 mW Operating Temperature Range T opr 0~+70 o C Storage Temperature Range T stg -65~+150 o C Operating Conditions Characteristics Symbol Min.
