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. 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. https://elecena.pl/product/27808003/ap431san1tr-g1-voltage-reference-2-5v-1-sot-23 2025-02-07 https://elecena.pl/product/27808003/ap431san1tr-g1-voltage-reference-2-5v-1-sot-23 2026-02-12
