Introduction

The LM337LM/NOPB is a three-terminal, low-dropout, adjustable voltage regulator from Texas Instruments. The chip provides a constant output voltage from its adjustable input voltage over a wide temperature range of -40 °C to +125 °C. It is designed for high precision and regulation.

Application field

The LM337LM/NOPB is designed for use in systems that require adjustable precise voltage regulation. It can be used in a wide range of applications such as: voltage references, battery chargers, overshoot protection, and works well to optimize circuit performance in any system design.

Working principle

The LM337LM/NOPB is a low dropout (LDO) adjustable three-terminal linear regulator. It features a wide input voltage range and precise output voltage regulation. The device operates by controlling the voltage across its output terminal, proportional to the voltage applied at its control terminal. It requires a capacitor to store energy and maintain the output voltage regulation over transient loads. The device is equipped with two power transistors: one forms the basis of the voltage reference and the other is used to control the output voltage. The output voltage is set by a resistor between the Adjust pin and ground. The Adjust voltage is compared to a reference voltage and its output is used to adjust the output voltage accordingly. The resulting voltage difference between the Adjust and Output pin is used to produce a current that is proportional to the output voltage, which is used to bias the power transistors and thus control the output voltage.

Conclusion

The LM337LM/NOPB is an excellent choice for applications requiring adjustable, precise voltage regulation. It has a wide temperature range, high precision, and low dropout preventing inaccurate readings in case of large voltage drops. It also has a wide input voltage range and can be used in a variety of applications, making it a versatile and cost-effective solution.
