FAQs
What is LM2990S-15?
The LM2990S-15 is a low dropout voltage regulator designed by Texas Instruments. It is specifically a 15V fixed output voltage regulator capable of providing a regulated DC voltage with low dropout voltage, making it ideal for applications requiring a stable power supply.
How Does LM2990S-15 Work?
The LM2990S-15 operates by regulating an input DC voltage to a fixed 15V output voltage with low dropout voltage. It uses internal circuitry to maintain a stable output voltage even when the input voltage varies. This regulator is designed to provide a constant and reliable power source for various electronic devices.
How Many Pins does LM2990S-15 have and What are the Functions of the Pinout Configuration?
The LM2990S-15 is housed in a 3-lead TO-220 package. The pinout configuration includes:
- INPUT: Input voltage pin.
- GND: Ground pin.
- OUTPUT: Regulated 15V output pin.
What are the Pros and Cons of LM2990S-15?
Pros:
- Low Dropout Voltage: Maintains regulation even when the input voltage is close to the output voltage.
- Fixed Output Voltage: Provides a stable 15V output voltage, eliminating the need for external voltage regulation circuitry.
- Thermal Protection: Includes built-in thermal shutdown protection for added reliability.
- Simple to Use: Requires minimal external components for operation, simplifying circuit design.
Cons:
- Fixed Output Voltage: The fixed 15V output may not be suitable for applications requiring variable output voltages.
- Heat Dissipation: As a linear regulator, it may dissipate more heat compared to switching regulators, especially for high input-output differentials.
Are There Any Equivalents/Alternatives to LM2990S-15 for Recommendation?
- The LM2940 from Texas Instruments is a similar low dropout voltage regulator with adjustable output voltage.
- Alternatives to the LM2990S-15 include the LT1086 from Analog Devices and the MCP1702 from Microchip Technology.
