L78S10CV datasheet by STMicroelectronics

L78S10CV Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L78S10CV can handle?
  The L78S10CV 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 L78S10CV 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 L78S10CV?
  The dropout voltage of the L78S10CV 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 L78S10CV in a high-temperature environment?
  The L78S10CV is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and input voltage according to the temperature derating curve in the datasheet.
• How do I protect the L78S10CV from input voltage surges?
  Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input to protect the L78S10CV from voltage surges and spikes.
