LT3083MPQ#PBF Application Field and Working Principle

Introduction to PMIC - Voltage Regulators - Linear

Power Management Integrated Circuits (PMICs) are electronic circuits designed to supply and regulate power for electronic circuits. They are composed of multiple power circuit components, such as switching regulators, linear regulators, converters and voltage regulators. Linear voltage regulators are the simplest form of voltage regulators. They are capable of providing a limited amount of current, up to a few Amperes.

Application of LT3083MPQ#PBF Linear Voltage Regulator

The LT3083MPQ#PBF is a high efficiency, low-dropout, wide input voltage range linear voltage regulator with a maximum output current of 1.5A. The device is available in a 5-lead SOT-23 package. Its wide 4.5V to 52V input voltage range makes it suitable for a variety of applications, such as automotive, telecommunication, security, industrial automation, HVAC and medical device. Its built-in reverse current protection, ESD protection, over-voltage protection and overtemperature protection make it suitable for use in harsh environment and for harsh application, where reliability is of critical importance.

Working Principle of LT3083MPQ#PBF Linear Voltage Regulator

The working principle of the LT3083MPQ#PBF linear voltage regulator is relatively simple. It is based on the principle of a voltage divider, where the input voltage is divided by a resistive divider, and the output is taken from the output of the resistive divider. The resistive divider is made up of P and N-Channel MOSFETs.When the input voltage is applied to the regulator, the P-Channel MOSFET acts as a current sink, and the N-Channel MOSFET as a source. The voltage across the resistor divider is determined by the input voltage and the two MOSFETs. The output voltage is taken from the output terminal of the resistor divider. The output voltage is adjusted by trimming the resistance of the resistive divider.The LT3083MPQ#PBF features a high PFET current limit of 1.5A with an adjustable lower current limit and an adjustable upper current limit. It also features thermal shutdown feature which shuts down the regulator automatically in case of over-temperature, over-voltage, or low input sinking current.

Conclusion

The LT3083MPQ#PBF is a high efficiency, low-dropout, wide input voltage range linear voltage regulator. Its wide input voltage range, low dropout voltage, and high current capacity make it suitable for a variety of applications such as automotive, telecommunication, security, HVAC and medical device. Its built-in reverse current protection, ESD protection, over-voltage protection and overtemperature protection make it suitable for use in harsh environment and for harsh application, where reliability is of critical importance. Furthermore, its working principle based on the principle of a voltage divider is simple and easy to understand.
