LP87702KRHBTQ1 Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the LP87702 datasheet (SLVSAC7) and the Power Management Guide (SLUAAC7). It's essential to follow these guidelines to ensure optimal thermal performance and minimize thermal resistance.
  • The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. TI recommends using a low-ESR capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the output voltage. Refer to the datasheet and the Capacitor Selection Guide (SLUAAC8) for more information.
  • The LP87702 has an absolute maximum input voltage rating of 18V. However, the recommended operating input voltage range is 2.7V to 15V. Exceeding the absolute maximum rating can damage the device.
  • The LP87702 has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) between the output pin and the GND pin. The device will limit the output current to the programmed value (set by the ILIM pin) when the voltage across Rs exceeds 50mV.
  • The EN (Enable) pin is used to turn the device on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled. Connect EN to a logic signal or a voltage source to control the device's operation.
