Datasheet Summary
ADJUSTABLE PRECISION ZENER SHUNT REGULATOR BL431
DESCRIPTION
Outline Drawing
The BL431 is a three-terminal adjustable regulator with a guaranteed thermal stability over applicable temperature ranges. The output voltage may be set to any value between VREF
(approximately 2.5V) and 36V with two external resistors. This device has typical dynamic output impedance of 0.2 Ω . Active output circuitry
TO-92
SOT23-3L provides a very sharp turn-on characteristic, making these devices excellent replacement for zener diodes in many applications.
