Voltage Regulator

Today, electronic devices have shrunken in size than ever before. This enables us to pack in tones of features in compact portable devices like smart watches, fitness trackers, and other wearable devices, it also helps us to deploy remote IoT devices for cattle monitoring, asset tracking etc. One common thing among all these portable devices is that they are battery operated…

Bleeder resistors are standard high value resistors which are used to discharge the capacitor in filter circuit. The discharging of the capacitors is really important because even if the power supply is OFF, a charged capacitor can give a shock to anybody. So it is really essential to add a bleeder resistor to avoid any mishaps. It also have other applications but the main…

When developing electronic projects, the power supply is one of the most important part of whole project and there is always need of multiple output voltage power supply. This is because different sensors need different input voltage and current to run efficiently. In this scenario, a power supply which can output multiple voltages becomes very important. There are options…

Just like situations in which we need to regulate the voltage in our designs, there are scenarios where we need to regulate the current that’s being supplied to a particular part of our circuit. Unlike transforming (changing from one voltage level to another), which is usually one of the major reasons for voltage regulation, current regulation is usually about keeping the…

Power is an important part of any electronics project/device. Irrespective of the source, there is usually a need to perform power management tasks like voltage transformation/scaling, and conversion (AC-DC / DC-DC) among others. Choosing the right solution for each of these tasks can be key to the success (or failure) of the product. One of the most common power management…

Voltage Regulator, as the name suggests, is a circuit that is used to regulate the voltage. Regulated voltage is a smooth supply of voltage, free from any noise or disturbance. The output from the voltage regulator is independent of load current, temperature, and AC line variation.  Engineers can create reliable power supply systems with the aid of these voltage…

Solenoids are very commonly used actuators in many process automation systems. There are many types of solenoids. For instance, there are solenoid valves which can be used to open or close water or gas pipelines, and there are solenoid plungers which are used to produce linear motion. One very common application of a solenoid that most of us would have come across is the…

Analog Devices launched LTM4661 a low power step-up µModule regulator in an ultrathin size 6.25mm x 6.25mm x 2.42mm BGA package.

LTM4661 requires only a few number of capacitor and resistor to complete the design. It takes only 1cm2 of area space single-sided or 0.5cm2 on double-sided PCBs. The Design includes a…

STLQ020 trade-offs between quiescent current, output power, dynamic response and package size to give designers extra freedom.

STLQ020 low-dropout (LDO) voltage regulator comes in smaller size with high performance and energy efficient. It’s ideal for use in battery-powered consumer products like tablets, smart phones, smart watches, and other…

Whenever we need a constant and specific value of voltage without fluctuation we use voltage regulator IC. They provide a fixed regulated power supply. We have 78XX (7805, 7806, 7812 etc) series voltage regulators for positive power supply and 79XX for negative power supply. But what if need to vary the power supply voltage, so here we have Variable Voltage Regulator IC…
