Introduction
The LM9036MMX-3.3 is a 3.3V linear regulator from National Semiconductor\'s fixed voltage family of voltage regulator products. The LM9036MMX-3.3 is a low-dropout (LDO) linear regulator that provides a regulated output voltage of 3.3V with a maximum supply voltage of 6 V. It is made on a monolithic CMOS process with an adjustable-ondemand low-noise, low-output ripple and low-power consumption performance.

The LM9036MMX-3.3 offers excellent load and line regulation, as well as good temperature stability. It is designed to meet the stringent requirements of mobile and power sensitive applications, and is widely used in portable devices and computers.

Application Fields
The LM9036MMX-3.3 offers high performance, low noise and low power consumption. It is suitable for a variety of applications, including:

• Cellular phones, PDAs and portable multimedia players
• Mobile computing
• LCD monitor and display backlighting
• Battery-powered equipment
• Portable desktop and handheld PCs
• Testing and measurement equipment
• Automotive and industrial equipment

The LM9036MMX-3.3 is extremely small and offers a wide temperature range classification of –40 to +85 °C, making it perfect for designs that must maintain small size while operating in extended temperature ranges.

Working Principle
The LM9036MMX-3.3 consists of a low-power series of pass elements and bandgap references that provide a highly efficient, temperature-stable, regulated output voltage. It employs current-mode control, which ensures the output voltage is constantly maintained, regardless of the load current.

The LM9036MMX-3.3 features an adjustable output voltage, as well as a 40 mV minimum dropout voltage. It also offers a guaranteed output current of 200mA and a maximum power dissipation of 1.3 W.

The output voltage of the LM9036MMX-3.3 is adjusted through the adjustment pin. This pin is connected to the output voltage through a voltage divider, and when the correct voltage is reached, it stops the adjustment cycle.

Conclusion
The LM9036MMX-3.3 is an ideal choice for applications that require an extremely low-voltage drop, low-noise and low power consumption. It is also suitable for portable and battery powered devices, as well as automotive and industrial applications. With its small size, wide temperature range classification and adjustable output voltage, it is a popular choice for many design applications.
