AP431SAN1TR-G1 Voltage reference, 2.5V, 1%, SOT-23

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.
