BCP68 datasheet by NXP Semiconductors

BCP68 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for BCP68?
  The recommended operating voltage range for BCP68 is 4.5V to 18V, although it can tolerate up to 20V for short periods.
• How do I ensure the BCP68 is properly biased for optimal performance?
  To ensure proper biasing, connect the base of the internal transistor to a voltage divider network that sets the base voltage to around 2.5V to 3.5V, depending on the application.
• What is the maximum current rating for the BCP68?
  The maximum current rating for the BCP68 is 1A, although it's recommended to keep the current below 500mA for reliable operation.
• Can I use the BCP68 as a switch or only as a linear regulator?
  The BCP68 can be used as both a switch and a linear regulator, depending on the application. However, it's more commonly used as a linear regulator due to its internal voltage reference and thermal protection.
• How do I protect the BCP68 from overheating?
  To protect the BCP68 from overheating, ensure good thermal conduction to a heat sink or PCB, and consider adding thermal protection circuitry, such as a thermistor or thermal fuse, to prevent damage.
