L78L24ACD datasheet by STMicroelectronics

L78L24ACD Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L78L24ACD?
  The maximum input voltage that can be applied to the L78L24ACD is 35V, although it's recommended to keep it below 30V for reliable operation.
• How do I ensure the L78L24ACD is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 2.2uF with an ESR (Equivalent Series Resistance) of less than 5 ohms, and keep the input capacitance as close to the regulator as possible.
• What is the minimum input voltage required for the L78L24ACD to regulate properly?
  The minimum input voltage required for the L78L24ACD to regulate properly is around 27V, although this can vary depending on the specific application and load conditions.
• Can I use the L78L24ACD in a high-temperature environment?
  The L78L24ACD is rated for operation up to 150°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I protect the L78L24ACD from input voltage surges or spikes?
  To protect the L78L24ACD from input voltage surges or spikes, use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor to clamp the voltage and prevent damage to the regulator.
