LP5861RSMR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to minimize thermal resistance. A minimum of 2 oz copper thickness is recommended for the top layer.
  • To ensure stable output voltage regulation, it's essential to decouple the input voltage with a capacitor (e.g., 10uF) and use a low-ESR output capacitor (e.g., 22uF). Additionally, ensure the input voltage is within the recommended range (2.7V to 5.5V) and the output voltage is set within the adjustable range (1.2V to 3.3V).
  • The LP5861RSMR can deliver up to 1A of output current. However, the maximum output current is dependent on the input voltage, output voltage, and ambient temperature. It's essential to consult the datasheet's thermal derating curves to determine the maximum output current for a specific application.
  • The LP5861RSMR has built-in overcurrent protection (OCP) and short-circuit protection (SCP). However, it's recommended to add external protection components, such as a fuse or a current-limiting resistor, to prevent damage from excessive current surges or faults.
  • Texas Instruments recommends using a low-ESR, X5R or X7R ceramic capacitor with a value of 10uF to 22uF for the input capacitor. This helps to filter out noise and ensure stable operation.
