Datasheet Diodes AN431BN-ATRE1

A Product Line of
Diodes Incorporated AN431
ADJUSTABLE PRECISION SHUNT REGULATORS Description Pin Assignments The AN431 series ICs are three-terminal adjustable shunt regulators
with guaranteed thermal stability over a full operation range. These
ICs feature sharp turn-on characteristics, low temperature coefficient
and low output impedance, which make them ideal substitutes for
Zener diodes in applications such as switching power supply, charger
and other adjustable regulators. (Top View) ANODE
3 The output voltage of these ICs can be set to any value between V REF
(2.5V) and the maximum cathode voltage (36V).
The AN431 precision reference is offered in two voltage tolerance:
0.5% and 1.0%. 1 2 CATHODE REF These ICs are available in SOT-23 package. Features SOT-23 Programmable Precise Output Voltage from 2.5V to 36V
