LP3986BL-3133

LP3986BL-3133 is a three-terminal voltage regulator designed to provide a fixed output voltage of 3.133V with a maximum output current of 200mA. The device features internal current limiting, thermal shutdown and reverse battery protection, which enable it to give predictable operation under most operating conditions. It also features low dropout voltage, low quiescent current and low heat dissipation, making it ideal for portable applications.

The LP3986BL-3133 is a positive voltage regulator, serving as a voltage regulator for positive voltage applications. It is one of the most basic types of voltage regulators known as linear voltage regulator, in contrast with the other two types of regulators that are switching regulators and switching converters. A linear voltage regulator works on a simple closed loop principle; it senses the input voltage and then compares it to a fixed reference voltage, which is already set for a particular application, and then produces an output voltage that is always equal to the reference voltage.

The LP3986BL-3133 is extremely versatile, as it can be used in numerous applications, including voltage regulators, power supplies and converters. It is also suitable for automotive systems, such as those found in cars, trucks and recreational vehicles. Other applications include industrial systems, medical systems, and consumer electronics products, such as televisions, radios and stereo system.

Using the LP3986BL-3133 as a voltage regulator requires three pins, namely the input voltage (supplied from the power source), the adjustable voltage (the output voltage) and the ground which acts as the reference voltage, as previously stated. During operation, the device senses the input voltage and compares it to the pre-set reference. If the input voltage is higher than the reference, the device will regulate the output voltage, reducing it so as to maintain the reference. The output voltage will be equal to the reference voltage in this case.

The LP3986BL-3133 also features internal current limiting, which prevents the output current from exceeding the set level. If the output current exceeds this level, the device will enter a safe operating mode, preventing the device from becoming damaged. Furthermore, it has thermal protection to prevent the voltage regulator from overheating if the power source for the device is overloaded.

The device also features reverse battery protection, which prevents the device from being damaged if reverse polarity is accidentally applied to it. This protection feature is especially important in applications such as automotive systems and industrial systems, where the presence of a reverse polarity can lead to the destruction of the device. The device also has low dropout voltage, which prevents it from becoming overloaded by the power source, and low quiescent current, which helps to reduce the amount of power it consumes.

In conclusion, the LP3986BL-3133 is an extremely powerful and reliable voltage regulator, which is suitable for all sorts of applications, ranging from automotive and industrial systems to consumer electronics and power supplies. Its many features, such as thermal protection, reverse battery protection, low dropout voltage and low quiescent current make it an ideal choice for a wide range of applications.
