The LM2936MX-3.0 is a 3.0V low dropout (LDO) voltage regulator from National Semiconductor (now Texas Instruments). It is designed to provide a stable and regulated 3.0V output voltage even when the input voltage is close to the output voltage. This LDO regulator is known for its low quiescent current and low dropout voltage.

Applications:

• Battery-powered systems
• Microcontroller power supplies
• Memory backup systems
• Portable devices
• Automotive applications

Features:

• Fixed 3.0V output: Provides a stable and regulated 3.0V output voltage.
• Low dropout voltage: Operates with a small difference between input and output voltage.
• Low quiescent current: Minimizes power consumption in standby mode.
• Reverse battery protection: Protects the regulator from damage if the battery is connected incorrectly.
• Short-circuit protection: Protects the regulator and load from short-circuit conditions.

Benefits:

• Extended battery life: Low quiescent current minimizes power consumption.
• Reliable operation: Built-in protection features ensure robust performance.
• Stable output voltage: Provides a consistent and regulated 3.0V output.
• Simple design: Requires few external components.
• Automotive-grade version available: Suitable for demanding automotive applications.

Additional Details:

The LM2936MX-3.0 can operate with an input voltage range of 5.5V to 40V and can supply up to 50mA of output current. It features a low dropout voltage of typically 0.2V at 50mA. The low quiescent current of typically 15µA makes it ideal for battery-powered applications. It is available in an 8-pin SOIC package. This regulator is commonly used in applications where low power consumption and stable voltage regulation are critical, such as in automotive electronics and portable devices.
