Texas Instruments recommends a compact layout with the device placed close to the battery, and the input capacitors (CIN) placed as close as possible to the VIN pin. Additionally, the output capacitors (COUT) should be placed close to the VOUT pin, and the device should be shielded from high-frequency noise sources.
To minimize IQ, ensure that the input voltage is within the recommended range (2.7V to 5.5V), use a low-value input capacitor (CIN), and minimize the output voltage (VOUT) to the lowest required value. Also, consider using the device's power-saving modes, such as the Low-Power Mode (LPM) or the Shutdown Mode (SDM).
The LP87702KRHBR can deliver up to 2A of output current, but this is dependent on the input voltage, output voltage, and ambient temperature. It's essential to consult the datasheet's electrical characteristics tables and thermal derating curves to determine the maximum output current for a specific application.
Proper thermal management is crucial for the LP87702KRHBR. Ensure good airflow around the device, use a thermally conductive PCB material, and consider using a heat sink or thermal pad. The device's thermal shutdown feature (TSD) will activate if the junction temperature exceeds 150°C, but it's still important to design for adequate heat dissipation.
The LP87702KRHBR is rated for operation up to 125°C, but its performance and reliability may degrade at higher temperatures. If your application requires operation above 125°C, consider using a different device or implementing additional thermal management measures, such as heat sinks or cooling systems.
