An adjustable shunt regulator offers excellent temperature stability and an output current handling capability up to 25mA. It features a low reference voltage of 1.24V, providing an output voltage range from 1.24V to 10V, with a maximum input voltage of 10V. This component achieves an initial accuracy of 1% and a temperature coefficient of 50 ppm/°C, supporting a shunt current capability from 100µA to 25mA. Optimized for low voltage applications and feedback control loops in switch-mode power supplies, it serves as a high-performance Zener diode replacement. Operating across a -40°C to +85°C range, the 3-pin device utilizes a shunt reference topology and is supplied in a SOT-23-3 surface mount package.
