LA431B

Adjustable Precision Shunt Voltage Regulator LA431A LA431B Adjustable Precision Shunt Regulator General Description LA431A and LA431B are three terminal Adjustable PrecisionShunt Regulators, With guaranteed thermal stability over a full operation temperature range. The output Voltage of these ICs can be set to any value between VREF (Typical 2.50V) and the corresponding maximum cathode voltage with two external resistors. These devices feature the sharp turn-on characteristics,low temperature coefficient and low output impedance, making them ideal substitute for Zener Diode in many applications such as switching power supplly, charger and other adjustable regulators. LA431 precision reference Voltage tolerance is offered in 2 grades:0.8% for LA431A and 0.4% for LA431B Both LA431A and LA431B are available in TO-92 (Bulk), TO-92 (Ammo),SOT-89, SOT-23 and SOT-23-5 packages.
