AP431S/AP431SH
LOW CATHODE CURRENT ADJUSTABLE PRECISION SHUNT REGULATOR Description Pin Assignments 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. (Top View) 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. (Top View) AN O D E ANODE 3 3 1 2 1 2 R EF C A TH O D E CATHODE REF SOT23 (Package Code: N)
The output voltage of the AP431S/AP431SH can be set to any value
between VREF (2.5V/2.495V) and the corresponding maximum SOT23 (Package Code: N1) (Top View) (Top View) cathode voltage (36V).
The AP431S/AP431SH is offered in two grade initial voltage
tolerance at +25°C, 0.5% and 1%.
