30 de abr. de 2021 · First, to answer your question, you want a PNP power transistor rated for at least twice the peak input voltage and twice the max output current. The transistor will see less than either of these max parameters, but that is design margin to increase reliability.
12 de feb. de 2018 · This letter reports on a fully integrated 2-A linear voltage regulator operational in a wide temperature range from 25 °C up to 500 °C fabricated in 4H-SiC technology. The circuit provides a stable output voltage with less than 1% variation in the entire temperature range.
The voltage across R B is the input voltage subtracting the V BE(sat). The maximum power dissipation is estimated as 38mW. In this post, I described the design guidelines for a robust, low-cost linear regulator with discrete components.
A linear regulator employs an active (BJT or MOSFET) pass device (series or shunt) controlled by a high gain differential amplifier. It compares the output voltage with a precise reference voltage and adjusts the pass device to maintain a constant output voltage.
The most important characteristic of the BJT is the plot of the collector current, IC, versus the collector-emitter voltage, V CE , for various values of the base current, I B as shown on the circuit of Figure 6.
A linear regulator employs an active (BJT or MOSFET) pass device (series or shunt) controlled by a high gain differential amplifier. It compares the output voltage with a precise reference voltage and adjusts the pass device to maintain a constant output voltage.
A voltage regulator with a transistor usually consists of a bipolar junction transistor (bjt) with high current handling capability in an emitter follower configuration, driven by zener diode and resistor potential divider (PD) network.
