AP431工业自动化与控制的液体过滤规格书PDF中文资料

DESCRIPTIOON

The AP431 is a low voltage three terminal adjustable shunt regulator with a guaranteed thermal stability over applicable temperature ranges. The output voltage can be set to any value between VREF (approximately 2.5 V) to 18V with two external resistors (see application circuit). This device has a typical output impedance of 0.2 Ω . Active output circuitry provides a very sharp turn on characteristic, making this device excel lent replacement for Zener diodes in many applications.
