PMIC (power management integrated circuits) are used to manage the power supply for different type of electronic systems, and voltage references are used to maintain a stable voltage reference for other circuits. LM336DR-2-5 is an adjustable 2.5V voltage reference designed by Texas Instruments.

The application fields of LM336DR-2-5 mainly include voltage regulating and voltage scaling applications. The device can be used to provide a regulated power source for any electronic circuits, such as regulators, amplifiers, and comparators. The device also provides precise input-output voltage scaling in order to adjust an amplitude between two signals.

The LM336DR-2-5 chip is mainly composed of two terminals. The positive terminal is connected to an external voltage source, which can range from 2V to 36V, the two negative terminal is connected to ground. The output range of the LM336DR-2-5 is between 2V and 2.5V, which can be adjusted by an external potentiometer. The output voltage can be tracked by an internal voltage regulator, thus keeping a constant voltage even when the input voltage changes.

The working principle of LM336DR-2-5 is based on the Zener diode principle, which states that when a voltage is applied to a p-n junction, a reverse current will flow, and thus a voltage drop across the junction can be obtained. The LM336DR-2-5 has a built-in Zener diode which will generate a 2.5V voltage drop when an external voltage is applied. The internal voltage regulator will keep the output voltage constant and resist any input voltage fluctuations.

In summary, the LM336DR-2-5 is an adjustable voltage reference chip used for voltage regulating and voltage scaling applications. The chip’s working principle is based on the Zener diode principle, which has a reverse current flowing when a voltage is applied across a p-n junction, thus generating a voltage drop. The chip’s internal voltage regulator maintains a constant output voltage even if the input voltage changes.
