LE40CZ
LE40CZ is a simple type of voltage regulator, also known as a linear regulator. It regulates the output voltage of the application by controlling the amount of current flowing from the input voltage into the output at a constant level. This type of regulator is ideal for applications where there is a fixed input voltage, such as automotive electronics and household appliances.
Application Field
LE40CZ voltage regulators are suitable for a wide range of applications. They are ideal for use in applications such as telecom systems, computer systems, audio and video equipment, automotive, industrial control, and home appliance systems. LE40CZ regulators provide stable power output and a high degree of protection against line-related noise, as well as a high degree of safety and reliability. They are also suitable for use as standalone power supplies in a variety of applications such as professional audio, industrial control and household appliances.
Working Principle
The working principle of the LE40CZ voltage regulator is relatively simple. It consists of an output capacitor (Cout) and a power transistor (Qprw). The power transistor is connected across the input supply and is used to regulate the output voltage. The voltage is controlled by adjusting the current flowing in the transistor, which is controlled by the output capacitor that is connected between the collector of the transistor and the load. The output capacitor acts as an energy storage device and allows the current to flow incrementally as needed to regulate the output voltage. When the output voltage reaches the preset level, the capacitor starts to discharge, regulating the current and output voltage. This process continues until the input voltage drops to zero or below, at which point the capacitor is fully discharged.
