LP2998QMR/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for switching regulator layout, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths.
  • To ensure stability, follow the recommended component values and PCB layout, and make sure the output capacitor has a low ESR (Equivalent Series Resistance). Additionally, adding a small ceramic capacitor (e.g., 10nF) between the VOUT and GND pins can help improve stability.
  • Although the datasheet specifies a maximum input voltage of 15V, it's recommended to limit the input voltage to 12V to ensure reliable operation and to prevent damage to the device.
  • The LP2998QMR/NOPB is rated for operation up to 125°C, but it's essential to consider the device's power dissipation and thermal management when operating in high-temperature environments. Ensure proper heat sinking and follow the recommended thermal design guidelines.
  • The output voltage of LP2998QMR/NOPB is adjustable using the resistive divider network (R1 and R2) connected to the VOUT pin. Use the formula: VOUT = 0.8V x (1 + R2/R1) to calculate the output voltage.
