L78L12ACUTR datasheet by STMicroelectronics

L78L12ACUTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L78L12ACUTR can handle?
  The L78L12ACUTR can handle a maximum input voltage of 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the L78L12ACUTR is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 2.2uF, and a minimum input capacitance of 0.33uF. Also, keep the input and output capacitors close to the regulator.
• What is the dropout voltage of the L78L12ACUTR?
  The dropout voltage of the L78L12ACUTR is around 2V, which means the input voltage should be at least 2V higher than the output voltage for proper regulation.
• Can I use the L78L12ACUTR in a high-temperature environment?
  The L78L12ACUTR is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and consider using a heat sink if operating in high-temperature environments.
• How do I protect the L78L12ACUTR from input voltage surges?
  Use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor to protect the L78L12ACUTR from input voltage surges and spikes.
