Part Details for TPS74801DRCRM3 by Texas Instruments

Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general best practices for LDO regulator layouts, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths.

The TPS74801DRCRM3 is stable with a wide range of output capacitors, but the datasheet recommends a minimum ESR (Equivalent Series Resistance) of 0.1 ohms and a minimum capacitance of 2.2 uF. For specific capacitor values, it's recommended to consult the capacitor manufacturer's datasheet and follow their recommended usage guidelines.

The absolute maximum input voltage rating for the TPS74801DRCRM3 is 15V, but the recommended operating input voltage range is 2.7V to 10V. Applying voltages above the recommended range can affect the device's performance and reliability.

The TPS74801DRCRM3 has a soft-start feature that helps to reduce inrush current during power-up. During power-down, the device's output voltage will decay rapidly to prevent any potential back-feeding of voltage into the input. The exact behavior may vary depending on the specific application and circuit design.

The TPS74801DRCRM3 has a thermal derating curve provided in the datasheet, which shows the maximum allowed power dissipation as a function of ambient temperature. The device's power dissipation should be derated according to this curve to ensure reliable operation over the desired temperature range.
