| FEATURES |
| – Programmable Output Voltage to 36V – Extended Cathode Current Range 80µA to 100mA – Low(Typ. 0.08Ω) Dynamic Output Impedance – Adjustable Output Voltage – Fast Turn-on Response – Low Output Noise – Excellent Temperature Coefficient 25ppm/°C – Moisture Sensitivity Level 3 |
| DESCRIPTION |
| The LP431 is a three-terminal adjustable shunt regulator with a specified thermal stability. The output voltage may be set to any value between VREF and 36V with two external resistors. The active output circuitry provides a very sharp turn-on characteristic making these devices an excellent replacement for Zener diodes in many applications, such as on board regulation, adjustable power supplies, and switching power supplies. |
