12.6V Negative Voltage Regulator using PNP Emitter Follower Before we use the just positive regulator as Simple DC regulator using transistor and Zener. The output voltage of this circuit is 12.6V. The output voltage of this circuit is 12.6V. We use PNP Transistor be main electronic parts. 12.6V voltage regulator using PNP emitter follower_Circuit ... Today we come to see12.6V Voltage Regulator Circuit.That usePNP Transistorbe main electronic part. By it very the circuit in the character emitter follower or voltage follower make have high current about 0.7 Amp. 12.6V voltage regulator using PNP emitter follower ... Today we come to see 12.6V Voltage Regulator Circuit. That use PNP Transistor be main electronic part. By it very the circuit in the character emitter follower or voltage follower make have high current about 0.7 Amp. PNP 2N2907 emitter follower voltage set by zener with 1N4148 rectifier diode offset cancellation This video is unavailable. Watch Queue Queue. Watch Queue Queue Emitter follower regulator with sziklai pair, transistor ... Now I'm using a bunch of LED's in parallel with 100ohm resistors as the testing load, and by drawing only 40mA the PNP transistor started to heat up considerably and I'm worried it would blow up if i draw more than a 100, also I'm concerned that the increased temperature might change the output voltage considerably due to decrease VBE according to Ebers Moll module. Bipolar Transistor Cookbook — Part 2 | Nuts & Volts Magazine In many applications, a “bidirectional” emitter follower circuit (that can source and sink currents with equal ease) is required, and this action can be obtained by using a complementary emitter follower configuration in which npn and pnp emitter followers are effectively wired in series. Biasing That Transistor: The Emitter Follower | Hackaday There’s a handy trick for reducing the voltage offset between an emitter follower’s input and output: put an NPN follower in series with a PNP follower. Assuming the NPN is the input, its ... Linear regulator using emitter follower and operational ... I have understood that you can create a linear regulator using a high current BJT power transistor in the emitter follower configuration and one operational amplifier (and a voltage reference, which can be a voltage source or some kind of Zener diode or similar). Transistor SeriesVoltage Regulator or Emitter Follower ... Transistor SeriesVoltage Regulator or Emitter Follower Voltage Regulator Emitter Follower Voltage Regulator Mohammad Burhan Votage regulator The efficiency of Zener regulated power supply becomes very low when the load current is high. PNP based linear regulator Page 1 EEVblog Hi all I'm trying to build a simple linear regulator that will output about 9V from an input of just above 9V up to maybe 70V. So that rules out using an LM317 or a 7809 as they only take an input of up to 40 volts. OpAmp Voltage Follower Regulator ImProgrammer 博客园 By using an emitter follower or a Darlington pair, a voltage follower op amp configuration can source higher currents than the op amp otherwise could. With high voltage regulators, powering the IC through the drive resistor for the pass transistors can become quite inefficient.
