Linear regulators for voltage regulation in a simple way

The linear stabilizers are the most simple in realization of a chip to adjust the voltage. Most elements of this type requiring only two external capacitors to filter the input and output voltage. The capacity of these elements depends on the current operation of the stabilizer and the bandwidth of its feedback loop.

Simple working principle of the chip linear regulator

The voltage regulator operates using a feedback loop to stabilize the voltage. By comparing the actual output voltage with a fixed reference voltage of the error amplifier, the system manages the Executive element, often a MOSFET transistor. Any difference voltage is amplified and used to control so that to reduce the error of the output voltage. This creates a loop the electronic feedback control. Given the nature of the feedback, the system is called linear regulators, as well as the fact that all component elements of the course feedback are linear systems. Considering the use of the transistor for voltage regulation by controlling the voltage drop across this element, a voltage stabilizer must be greater than the output voltage.

Stabilizers - Easy to implement, electronic components

Implementation of linear stabilizers in electronic circuits is extremely easy, given the fact that the currently available modern voltage regulators are highly integrated circuits containing in its structure all necessary elements and control element (transistor), error amplifier and reference voltage. Due to the fact that the implementation of these systems does not require time-consuming calculations or experimental values fitting the electronic components that accompany the system.

Voltage regulator - a Simple selection of appropriate elements

Given the simplicity of the circuits of the voltage regulators selection of elements external to the system extremely easy. Most often a linear regulator requires only two, associated passive electronic components - capacitor input and output capacitor. Capacity at the input of the system the task is to filter the supply voltage for the linear regulator.

It is assumed that the capacitor at the input linear regulator must have a capacity of 1000 microfarads at 1 amp passing current. In this place it would be good to put a capacitor of low series resistance reception (ESR). To reduce the resistance of the filter, the capacity that can be divided into several containers, for example, 1000 UF, 1 UF, 100 NF and 1 NF in parallel. Because of this, gets the filter with low resistance in a wide range of frequencies, which will improve the quality of the output voltage of the voltage regulator.

The output capacitor is selected in turn, in accordance with the guiding card directory. This item is part of a feedback loop in a linear regulator that has an effect on her runway, therefore you need to choose the electronic element on the container, not to exceed psma feedback voltage regulator, which is also dependent on other elements contained in the structure of the chip. Typically, the sheet of the electronic element specifies what is the minimum output capacitance for the linear regulator.

Preprogramowane and adjustable voltage regulators

The majority of commercially available linear stabilizers is characterized by the factory installed level of the output voltage. Part of the voltage regulators may, however, also in version programmable from the outside, ie one where you can adjust the output voltage. Most often, this element e is performed by adding the two resistors in the circuit of the voltage divider. The voltage output is then on a special measurement input linear regulator and then to the error amplifier and control system. The exact mathematical relationships between the heating elements of these resistors, and the output voltage can be found in the Datasheet of this voltage regulator.
