PJ431/PJ431A/PJ431B Programmable Precision References diodes in many applications such as digital voltmeters, power supplies , and op amp circuitry. The 2.5 volt reference makes it convenient to obtain a stable reference from 5.0 volt logic supplies, and since The PJ431, A, B operates as a shunt regulator, it can be used as either a positive or negative tage reference. IC voltage references operate as a low temperature coefficient zener which is programmable from Vref to 36 volts with two external resistors. These devices exhibit a wide operating current range of 1.0 to 100mA with a impedance typical dynamic these of 0.22Ω. The characteristics of T he PJ431, A, B integrated circuits are three-terminal programmable shunt regulator diodes. These monolithic references make them excellent replacements for zener FEATURES TO-92 SOT-89 • • Programmable Output Voltage to 36 Volts Voltage Reference Tolerance: PJ431A : ±0.5%, Typ@25°C PJ431 : ±1%, Typ@25°C Pin: 1.

Reference 2. Anode 3. Cathode (Heatsink surface connected to Pin 2) SOT-23 BLOCK DIAGRAM Pin: 1. Reference 2. Cathode 3. Anode SOP-8 is an internally modified SOP-8 Package. Pins 2,3,6 and 7 are electrically common to the die attach flag. This internal lead frame modification decreases package thermal resistance and increases power dissipation capability when appropriately mounted on a printed on a printed circuit board. SOP-8 conforms to all external dimensions of the standard SOP-8 Package. CIRCUIT SCHEMATIC QRDERING INFORMATION Device PJ431/ [ … ]
