Series pass regulator

Series voltage regulators explained. Simple series regulators, zener diode action, feedback, current limiting and over volts protection. The series regulator or series pass regulator is the most widely used form of linear regulator. Here, the load current IRis supplied by the transistor whose base is now connected to the Zener diode.

The output voltage of the series regulator is Vout = Vzener – Vbe.

The load current Iload of the circuit will be the maximum emitter current that the transistor can pass.

If the load current is zero or has no value, then the current drawn .

Because the total load current passes through this transistor, it is sometimes called a pass transistor. Other components which make up the circuit . Linear voltage regulators control the voltage drop between input and output as needed to set the desired output voltage. On this channel you can get education and knowledge for general issues and topics.

THE SERIES -PASS VOLTAGE REGULATOR. Learn how series -pass voltage regulator circuits are designed. Gain experience in making power supply performance measurements.

It is used (or at least, quite similar circuits) in many popular ICs such as the L. Since the diode is connected to the transistor, VZener voltage is also applied to the . We have not processed the video so that it remain. Transistor voltage regulator and ripple filter circuits explained - Duration: :56. It regulates by adjusting its internal resistance such that VIN . There are two kinds of zener controlled transistor voltage regulators. Due to the logarithmic shape of diode V-I curves, the voltage across the diode changes only slightly due to changes in current drawn or changes in the input. When precise voltage control and efficiency are not . Sorry, I exchanged it with the effective capacitance that the electronic circuit sees.

Vz due to temperature variations appear at the output since the transistor is connected in series with loa it is called series regulator and transistor is allow series pass transistor. The circuit works this way :- Iis the collector current of Q and hence it is also . There are some advantages of transistor series voltage regulator are given below , The transistor series voltage regulator has output voltage remains consta. Three basic components are needed to achieve good voltage regulation.

Hi, I have been trying to analyse the attached circuit.
