LM431ACM3

The LM431ACM3 is an adjustable precision shunt regulator diode typically used in power management and voltage reference applications. It is found in a variety of electronic devices, such as computers, televisions, DVD players, and other electronic products. The LM431ACM3 is designed to perform extremely high precision voltage regulation and is ideal for use in power management systems.

The LM431ACM3 operates by adjusting its own shunt resistance, as opposed to relying on external resistors to accommodate a desired voltage. It uses an internal reference voltage of 1.25V to generate a shunt regulation voltage which is adjustable over a range of 1.2 to 20V. The regulator is extremely accurate, with initial accuracy of 0.25% and the ability to adjust the voltage with an external potentiometer down to 0.01%. The LM431ACM3 also offers good thermal stability, with a temperature coefficient of +100ppm/°C.

The LM431ACM3 can be used in a variety of power management and voltage reference applications, such as battery chargers, AC/DC converters, dc/dc converters, and hot-swap voltage sources. It can also be used in DC-DC converters to regulate voltage from a wide range of AC-to-DC sources, such as solar panels and alternators. The LM431ACM3 is ideal for use in power management systems to deliver precise, consistent voltage.

The LM431ACM3 is easy to use and set up. It is typically connected in series between the input and output of the desired circuit, providing a single-chip solution for voltage regulation. Once connected, the external potentiometer can be used to adjust the output voltage to the desired setting. The LM431ACM3 is also designed to be extremely energy efficient, with a low quiescent voltage and current.

The LM431ACM3 is an ideal solution for power management and voltage reference applications, offering precision, accuracy, and temperature stability. Its efficient operation and simple setup make it suitable for use in a wide range of devices. Its adjustable shunt resistance makes it easy to achieve the desired voltage level, and its extremely accurate initial accuracy makes it ideal for use in power management systems.
