LP2996LQ/NOPB datasheet by Texas Instruments

LP2996LQ/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2996LQ/NOPB?
  The maximum input voltage that can be applied to the LP2996LQ/NOPB is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent damage to the device.
• How do I ensure the LP2996LQ/NOPB is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and add a 10nF capacitor between the VIN and GND pins. Also, avoid using long traces and keep the input and output capacitors close to the device.
• What is the minimum input voltage required for the LP2996LQ/NOPB to operate?
  The minimum input voltage required for the LP2996LQ/NOPB to operate is 2.5V, but it's recommended to keep it above 3V for optimal performance.
• Can I use the LP2996LQ/NOPB in a high-temperature environment?
  The LP2996LQ/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to prevent overheating and ensure reliable operation.
• How do I calculate the output voltage of the LP2996LQ/NOPB?
  The output voltage of the LP2996LQ/NOPB is adjustable and can be calculated using the formula: VOUT = 1.24V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
