LP38692MPX-1.8/NOPB datasheet by Texas Instruments

LP38692MPX-1.8/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general best practices for low-dropout regulator (LDO) layouts, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths.
• How do I ensure stability with a specific output capacitor?
  To ensure stability, the output capacitor should meet the minimum ESR (Equivalent Series Resistance) and capacitance requirements specified in the datasheet. Additionally, the capacitor should be placed close to the device and the PCB layout should be designed to minimize parasitic inductance and resistance.
• What is the maximum input voltage that can be applied to the device?
  The maximum input voltage that can be applied to the LP38692MPX-1.8/NOPB is 7V, as specified in the datasheet. Exceeding this voltage may cause damage to the device or affect its performance.
• How does the device behave during power-up and power-down sequences?
  The LP38692MPX-1.8/NOPB has a soft-start feature that helps to reduce inrush current during power-up. During power-down, the device will shut down and enter a low-quiescent current state. The exact behavior may vary depending on the specific application and circuit design.
• What is the thermal derating of the device?
  The thermal derating of the LP38692MPX-1.8/NOPB is specified in the datasheet and is typically around 20mA/°C above 25°C. This means that the device's output current capability will decrease as the temperature increases.
