UA78L12ACLPE3 Frequently Asked Questions (FAQ)

  • The UA78L12ACLPE3 can handle a maximum input voltage of 35V, but it's recommended to keep it below 25V for optimal performance and to prevent overheating.

  • The output voltage of the UA78L12ACLPE3 is fixed at 12V, and it's not adjustable. The output voltage tolerance is ±4% over the entire operating temperature range.

  • The minimum input voltage required for the UA78L12ACLPE3 to operate is 14.5V, but it's recommended to keep it above 15V for optimal performance.

  • The UA78L12ACLPE3 is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for optimal performance and reliability. You may need to add heat sinks or thermal management solutions for high-temperature applications.

  • To ensure stability, make sure to follow the recommended PCB layout and component placement guidelines, and add a 10uF capacitor at the input and a 22uF capacitor at the output. You can also add a 1uF capacitor at the output for additional stability.
