NJM8068RB1-TE1 - Nisshinbo

NJM8068RB1-TE1 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  The recommended PCB layout for optimal thermal performance involves placing thermal vias under the IC, using a solid ground plane, and keeping the thermal path as short as possible. A 4-layer PCB with a thermal layer is also recommended.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it is recommended to use a capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. The output capacitor should also be placed as close to the IC as possible.
• What is the maximum input voltage that can be applied to the NJM8068RB1-TE1?
  Although the datasheet specifies a maximum input voltage of 18V, it is recommended to limit the input voltage to 15V to ensure reliable operation and to prevent damage to the IC.
• How do I protect the NJM8068RB1-TE1 from overcurrent and overheating?
  To protect the NJM8068RB1-TE1 from overcurrent and overheating, it is recommended to add an overcurrent protection circuit and a thermal shutdown circuit. The overcurrent protection circuit can be implemented using a sense resistor and a comparator, while the thermal shutdown circuit can be implemented using a thermistor and a comparator.
• What is the recommended input capacitor value and type?
  The recommended input capacitor value is 10uF to 22uF, and the recommended type is a ceramic capacitor with a low ESR and a high ripple current rating. The input capacitor should be placed as close to the IC as possible.
