TL431BCLP Shunt Regulator – TO-92-3

The TL431BCLP is a three terminal adjustable shunt regulator. It has specified thermal stability over applicable automotive, commercial, and military temperature ranges. Its output voltage can also be set to any value between V_ref (approximately 2.5 V) and 36 V, with two external resistors. It also has output impedance of 0.2 Ohms. Its Active output circuitry provides very sharp turn on characteristics. And so makes it excellent replacement for Zener Diode in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies. The TL431BCLP has  operating temperature range of 0° to 70° C.
