AP431S Datasheet | Diodes Incorporated

Description The AP431S/AP431SH is a 3-terminal adjustable shunt regulator with guaranteed thermal stability over a full operation range. It features sharp turn-on characteristics, low-temperature coefficient and low output impedance, which makes it ideal substitute for Zener diode in applications such as switching power supply, charger and other adjustable regulators. Pin Assignments (Top View) ANO DE 3 (Top View) ANODE The AP431S/AP431SH has the same electrical specifications as the industry standard 431 except that it features a low minimum cathode current for regulation. The typical value of 50μA makes the parts ideal for very low power dissipation applications. The output voltage of the AP431S/AP431SH can be set to any value between VREF (2.5V/2.495V) and the corresponding maximum cathode voltage (36V). C ATH O D E SOT23 (Package Code: N) (Top View) CATHODE SOT23 (Package Code: N1) (Top View) The AP431S/AP431SH is offered in two grade initial voltage tolerance at +25°C, 0.5% and 1%.
