![]() Fundamentally, the transistor voltage regulators which are controlled by Zener are classified into two types namely series voltage regulators and shunt voltage regulators. Most of linear VRs perform their voltage regulating function with a single voltage supply, but only a few can achieve the combination of wide power supply range, low noise, fast transient, high load capability, and extra protection features 2, 3, 4. Beneath these conditions, a transistor-like Zener controlled is used frequently to maintain o/p voltage stable. It also must protect the load and system in case of a component failure. It needs to meet the load voltage or current regulation requirement during steady-state and transient conditions. Thus, the Zener RPS ( regulated power supply)efficiency turns into extremely low as the load current is high. A power converter generates output voltage and current for the load from a given input power source. The LR8 is available in a TO-92 package and typically costs about sixty cents in small quantities. Its maximum current is 20 mA, so any substantial supply requires a pass transistor here, a TIP50. It is not simple to modify the o/p voltage because no such resources are provided. Its output voltage is set by a voltage divider across its output as with lower voltage regulators its maximum output is 12V less than its input.IC switching voltage regulators store energy. This occurs due to both VZ & VBE reduce by the rise in room temperature. IC linear voltage regulators use an active pass element to reduce the input voltage to a regulated output voltage. The adjustments within Zener current are decreased to a significant amount the amount produced is not completely stable.Voltage regulators may be mechanical, electric, AC, or DC. Then, the regulated voltage will come out to the load. As the circuit diagram below, The input terminal wants an unregulated DC supply,15V to 20V. The series voltage regulator disadvantages are listed below. A voltage regulator is a device used to change fluctuating voltages on its input to a defined and stable one on its output. It is a series voltage regulator because the load current passes through the series transistor. Therefore, the Zener impedance effect will be decreased extremely & we can get an additional stabilized output. In prior emitter-follower voltage regulators, zener diodes, which have the characteristics of good voltage regulation and low-current requirement, have been. The main benefit of this voltage regulator circuit is, the changes within Zener current are decreased through a factor ‘ß’. ![]() By changing the resistance of the series. The advantages of this series voltage regulator are listed below. The series voltage regulator or series pass voltage regulator uses a variable element placed in series with the load. ![]()
