Introduction to PMIC - Voltage Reference

A voltage reference is a circuit that provides a stable reference voltage. It is used to provide a stable voltage source for an analog circuit or as a calibration standard for other measurement devices. Voltage references have traditionally been used in power supply design and analog circuit design, but they are now widely used in digital systems and microcontroller applications.PMIC–Voltage Reference is a power management integrated circuit (PMIC) that is optimized for providing a stable reference voltage. The PMIC – Voltage Reference family of devices usually have multiple voltage channels, a range of circuitry options, and a variety of features for different applications. LT6654BHS6-3.3#TRMPBF is an example of a PMIC – Voltage Reference from Linear Technology.

Working Principle of LT6654BHS6-3.3#TRMPBF

The LT6654BHS6-3.3#TRMPBF uses a low-dropout voltage reference (LDO) topology. A typical LDO is a linear regulator that uses an external power supply to regulate the output voltage. The voltage reference circuit uses an internal reference voltage (VREF) to compare the feedback voltage and adjust the output voltage accordingly.The LT6654BHS6-3.3#TRMPBF is an adjustable voltage reference. It uses a low-dropout voltage reference (LDO) topology, but with an adjustable reference voltage. It features two external resistors that set the reference voltage, one for the lower end of the output voltage range and one for the higher end. The reference voltage can be adjusted by changing the resistance of the two external resistors.
