RN1502(TE85L,F) - Toshiba

RN1502(TE85L,F) Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A thermal pad is recommended under the IC, and a solid ground plane on the bottom layer can help to dissipate heat. Additionally, keeping the thermal path short and using thermal vias can improve thermal performance.
• How do I ensure stable operation with a high-ESR output capacitor?
  To ensure stable operation with a high-ESR output capacitor, it's recommended to add a small ceramic capacitor (e.g., 10nF) in parallel with the output capacitor to reduce the overall ESR.
• What is the maximum allowed voltage on the EN pin?
  The maximum allowed voltage on the EN pin is 6V, exceeding which may cause damage to the IC.
• Can I use the RN1502 in a high-temperature environment?
  While the RN1502 is rated for operation up to 85°C, it's recommended to derate the output current and consider additional thermal design considerations for high-temperature applications.
• How do I calculate the output voltage tolerance?
  The output voltage tolerance can be calculated by considering the internal voltage reference tolerance (±1.5%), the resistor tolerance (±1%), and the output voltage adjustment range (±4%).
