The LM140K-5.0/NOPB voltage regulator belongs to the category of linear voltage regulators. This type of regulator allows output from 5V to 25V in several linear adjustments. These adjustments are usually 0 (Fixed), 1 (Adjustable) and 2 (ADJ). The regulated voltage is adjustable by a single resistor. Voltage regulation is achieved by varying the applied current or by varying the sense voltage. This system reduces the “on” or “off” type of switching between two different voltage levels, thereby providing very precise voltage regulation.

The LM140K-5.0/NOPB has a maximum quiescent current of 4mA and a maximum dynamic load current of in the order of 3A. Due to its high efficiency, it has lower operating current and at the same time, offers up to 50% more power than other linear regulators. It also supports up to 10V input over temperature range and includes thermal protection.

The LM140K-5.0/NOPB regulator has many applications including memory protection, system power supplies, automotive electronics, general purpose power supplies, switching power supplies and medical devices. It can be used to control the voltage of computer systems, mobile devices, audio amplifiers and gaming devices. In addition, this regulator can be used to stabilize the power supply of home appliances and other electrical devices.

The LM140K-5.0/NOPB regulator works on the principle of maintaining a constant voltage by using a negative feedback network. It uses an internally fixed reference voltage to compare it with the output voltage. The difference between the reference and output voltage is called the “error voltage”. If the error voltage increases, the LM140K-5.0/NOPB increases its output current to reduce the error voltage and thereby maintain the output voltage.

The external components used in the circuitry of the LM140K-5.0/NOPB are resistors and capacitors. The resistors are used to provide feedback signals and to establish the required tension for the regulator. The capacitors are used to store energy or to reduce output ripple and noise.

The LM140K-5.0/NOPB regulator is an excellent choice for applications that require a precise and stable output voltage. It can be used in a variety of applications, ranging from system power supplies to medical devices and home appliances. With its high efficiency and good regulation characteristics, it provides effective and reliable voltage regulation.
