Frequently Asked Questions
What is the output voltage and maximum output current of LM2937ES-5.0?
The LM2937ES-5.0 provides a fixed 5V regulated output voltage with a maximum output current of 500mA. The output voltage accuracy is ±1%, making it suitable for powering precision analog and digital circuits.
What is the dropout voltage of the LM2937ES-5.0 and why does it matter?
The LM2937ES-5.0 has a typical dropout voltage of 0.5V and a maximum of 1V. This low dropout means the input voltage only needs to be 0.5–1V higher than the 5V output, reducing power dissipation and extending battery life in portable applications.
What package is the LM2937ES-5.0 and what are common applications?
The LM2937ES-5.0 is available in the TO-263 (D2PAK) surface-mount package, which offers excellent thermal dissipation. It is commonly used in automotive electronics, industrial control boards, microcontroller power rails, and consumer electronics requiring a reliable 5V supply.
What are suitable replacements or alternatives for the LM2937ES-5.0?
Compatible alternatives include the LM1117-5.0 (SOT-223), LT1963A-5 from Analog Devices, and the AMS1117-5.0. When substituting, ensure the replacement matches the 5V output, 500mA current rating, dropout voltage, and package footprint requirements of your design.
