The LM336M-2.5 is a voltage reference chip designed specifically for use in power management integrated circuits (PMICs). It was developed by National Semiconductor Corporation as an alternative to traditional voltage regulation techniques.

The LM336M-2.5 is based off the company’s once-popular LM336 family of voltage references. But unlike its predecessors, the LM336M-2.5 has been modified to provide improved accuracy, settling time, and temperature stability. This makes it ideal for applications such as AMR, PMR, and buck converters, among others.

The LM336M-2.5 operates using a three-terminal design and features two voltage outputs. The first output, VREF, acts as the reference voltage while the second output, VTH, receives the output current. The chip also features a third terminal, GND, which is used to ground the unit. This allows for efficient regulation of both regulated and unregulated power supplies.

At the heart of the LM336M-2.5’s technology is a band-gap reference circuit. This circuit works by comparing the voltage set at the VREF terminal with a small voltage generated by a voltage divider. When these two voltages are equal, the output current is regulated, providing a stable reference voltage.

The LM336M-2.5 is highly accurate over a wide range of temperatures, from -40°C to 125°C. It also features a fast settling time and a wide range of accepted supply voltages between +2.5V and +32V. This makes it an ideal choice for a wide range of PMIC applications.

The LM336M-2.5, thanks to its advanced design, provides a reliable voltage reference and is ideal for applications such as power-grid regulation, AC/DC power supplies, digital and analog control circuits, and microcontrollers. In addition, its high accuracy over varying temperatures makes it suitable for automotive applications.

The LM336M-2.5 is a powerful tool for power management applications, offering a low noise, highly accurate voltage reference chip in a compact package. It’s easy to use and cost-effective, making it the ideal choice for any PMIC application.
