A regulated power supply is very much essential for several electronic devices due to the semiconductor material employed in them have a fixed rate of current as well as voltage. Hi steve, The problem is that maximum base emitter voltage of 2N is 7V. People here would be much better able to help you if you explained what you want to do. If you want 1A to flow in the resistor, the resistor needs to be 11 ohms. If the regulator does not have a heat sink to dissipate this heat, it can get destroyed and malfunction.
In this tutorial, we will see about one of the most commonly used regulator IC’s, the Voltage Regulator IC.
Voltage Regulator IC Pinout, Diagrams, Equivalent & Datasheet
It is an IC in the 78XX family of linear voltage regulators that produce a regulated 5V as output. is a three terminal linear voltage regulator IC with a fixed. You want a PNP type. That type sources current.
If you need to use an existing schematic. The proper choice of R1/R2/Q2 depends on the. IC is an iconic regulator IC that finds its application in most of the projects. The name signifies two Voltage regulators are very common in electronic circuits.

For a 10A output, 9A via the boost transistors. You can see the circuit in the attachment.
Voltage Regulator IC Circuit Working and Applications
Look what happens if you build it with resistors calculated for the transistors having a beta of and a Vbe of 1. The circuit is made up of transformer, bridge rectifier made up from diodes, linear voltage regulator and capacitors.
published 4 What is the PNP bipolar transistor function on the circuit?. Jun 29, PNP Transistors - BC / BC / BC / BC / BC We can see pinout and example circuit which easies to builds with PCB.
