UA78L08ACDRG4 datasheet by Texas Instruments

UA78L08ACDRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the UA78L08ACDRG4 can handle?
  The UA78L08ACDRG4 can handle input voltages up to 35V, but it's recommended to operate within the specified input voltage range of 7V to 25V for optimal performance and reliability.
• How do I ensure the UA78L08ACDRG4 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor (e.g., 10uF to 22uF) and a minimum ESR of 0.5 ohms. Additionally, keep the input and output capacitors close to the device and use short, direct traces to minimize inductance.
• What is the maximum output current that the UA78L08ACDRG4 can provide?
  The UA78L08ACDRG4 can provide up to 2A of output current, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
• How do I protect the UA78L08ACDRG4 from overvoltage and undervoltage conditions?
  You can use external voltage protection circuits, such as a voltage supervisor or a crowbar circuit, to protect the UA78L08ACDRG4 from overvoltage and undervoltage conditions. Additionally, consider using a TVS diode or a zener diode to clamp the input voltage to a safe level.
• What is the thermal shutdown temperature of the UA78L08ACDRG4?
  The UA78L08ACDRG4 has a thermal shutdown temperature of around 150°C to 170°C, which helps prevent damage from overheating. However, it's essential to ensure good thermal design and heat dissipation to prevent the device from reaching this temperature.
