PMIC stands for Power Management ICs and voltage regulators, such as LINEAR, are an integral part of the day-to-day operations, delivering quality and reliability in products that require power. The REG101NA-A/3K is a 3.3V, 100mA low dropout linear regulator. It is specified over a wide range of operating conditions, making it an attractive choice for applications that require tight regulation and excellent current limiting performance.

The REG101NA-A/3K device is a low quiescent current, low dropout voltage, linear regulator. It comes in a three-terminal SOT-23 package and operates over a wide input voltage range. The device has an enable pin with an active-low level logic. When the enable pin is at a logic high level, the output is switched off; when the enable pin is at a logic low level, the regulator is enabled. The output voltage can be externally set with a single resistor to any value between 1.25V and 6.0V.

The working principle of the REG101NA-A/3K is basic. The input voltage is applied to the VIN pin, and the output voltage is adjusted to the desired value by adjusting the value of the external resistor. The output is then regulated at the set value. The current passing through the resistor creates a voltage drop across it, which is then compared to the reference voltage. When the voltage drop is equal to or greater than the reference voltage, the output is regulated at the set level.

The REG101NA-A/3K is a great choice for applications where low quiescent current, high output accuracy and low dropout voltage are required. Its enable pin also allows for easy connection to other logic elements. It is particularly suited for battery-powered systems as well as for portable communication, measurements and display applications. It is also suitable for automotive, industrial and consumer applications.

In summary, the REG101NA-A/3K linear regulator delivers quality and reliability in products that require power. It is suitable for a wide variety of applications and its enable pin allows for easy connection to other logic elements. It is also equipped with a low quiescent current, low dropout voltage and high output accuracy, making it an ideal choice for systems with stringent power requirements.
