The LM2940IMP-5.0/NOPB is a low dropout regulator (LDO) manufactured by Texas Instruments (TI). It is specifically designed to provide a regulated output voltage with low dropout and low quiescent current. It is a reliable and efficient regulator with low dropout and low quiescent current. Its compact TO-220 package and powerful features make it suitable for a wide range of applications requiring a stable and regulated 5.0V supply.


The LM2940IMP-5.0/NOPB is designed to regulate an input voltage and provide a regulated 5.0V output voltage. It operates as a linear regulator, which means it dissipates excess energy as heat to maintain the desired output voltage.

Main features:

1. Low dropout voltage: The LM2940IMP-5.0/NOPB has a very low dropout voltage of 0.5V typical at a load current of 1A, enabling regulation even with small voltage differences between input and output.

2. Low quiescent current: Low quiescent current with a typical value of 10mA ensures extremely low power consumption at light load.

3. Thermal Shutdown Protection: The regulator includes thermal shutdown protection, which automatically shuts down the device if the temperature exceeds safe operating limits.

4. Short circuit protection: It combines current limiting and short circuit protection to protect the voltage regulator and connected circuits in the event of a fault.

5. Wide operating temperature range: The LM2940IMP-5.0/NOPB operates reliably over a wide temperature range, typically -40°C to 125°C.

6. TO-220 package: Adopt TO-220 package, which provides excellent heat dissipation and easy installation.


The LM2940IMP-5.0/NOPB is commonly used in various electronic applications requiring a regulated 5.0V power supply. Some typical applications include:

1. Automotive electronics: Can be used to power microcontrollers, sensors, and other components in automotive systems.

2. Battery-powered devices: Voltage regulators are suitable for portable devices such as handheld instruments, consumer electronics, and battery-powered gadgets.

3. Industrial control system: It can provide regulated voltage for the control board, sensor and actuator in the industrial automation control system.

4. Embedded systems: The LM2940IMP-5.0/NOPB can be used in embedded systems, including microcontroller-based projects and development boards.

5. Power Module: It can be used as a building block for low-power, 5.0V power modules in various applications.
