R1283K002C-TR Frequently Asked Questions (FAQs)

  • Ricoh recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • To ensure stable output voltage regulation, it's essential to follow the recommended input and output capacitor values, and to decouple the input voltage with a capacitor. Additionally, the output voltage should be filtered with a capacitor to reduce noise.
  • The maximum allowed input voltage ripple is 100mVp-p. Exceeding this value may affect the regulator's performance and stability.
  • The R1283K002C-TR is rated for operation up to 125°C. However, the output current may need to be derated at higher temperatures to prevent overheating. Consult the datasheet for specific derating curves.
  • The R1283K002C-TR has built-in overcurrent protection (OCP) and short-circuit protection (SCP). However, it's still recommended to add external protection components, such as fuses or PTC resistors, to prevent damage from excessive current or voltage.
