DESCRIPTION

The A431L is a three-terminal Adjustable Shunt Voltage Reference. Output can be set to any value between VREF (1.24V) and 18V with two external resistors (see Figure 2).

The A431L operate from a lower voltage (1.24V) than the widely use A431, A431A and A432A shunt-regulator reference.

The A431L has a typical output impedance of 0.5Ω. Active output circuitry provides a very sharp turn-on characteristic, making A431L excellent replacements for Zener diodes in many applications, including on-board regulation and adjustable power supplies.

The A431L is available in SOT-23 package.
