ROHM recommends a thermal pad size of at least 2.5mm x 2.5mm with multiple vias to the ground plane to ensure efficient heat dissipation. A thermal resistance of 10°C/W or less is recommended.
To prevent oscillation, ensure that the input capacitor (CIN) is placed close to the VIN pin, and the output capacitor (COUT) is placed close to the VOUT pin. Additionally, use a low-ESR capacitor for COUT and ensure the PCB layout is symmetrical to minimize parasitic inductance.
The maximum allowable voltage for the EN pin is 6V. Exceeding this voltage may damage the internal circuitry. It's recommended to use a voltage divider or a level shifter if the control signal exceeds 6V.
While the LTR18EZPFLR130 is rated for operation up to 105°C, it's essential to consider the derating of the output current and voltage at high temperatures. Consult the datasheet and ROHM's application notes for guidance on high-temperature operation.
The output current accuracy and tolerance can be calculated using the formulae provided in the datasheet. Consider the internal reference voltage tolerance, resistor tolerance, and temperature coefficient to determine the overall output current accuracy.
