PRODUCTION DATA
The TPSM843820E is designed to operate from an input voltage supply range between 4V and 18V. This supply voltage must be well regulated. Proper bypassing of the input supply is critical for proper electrical performance, as is the PCB layout and the grounding scheme. A minimum of 4μF (after derating) ceramic capacitance, type X5R or better, must be placed near the device. TI recommends splitting the ceramic input capacitance equally between the VIN and PGND pins on each side of the device resulting in at least 2µF of ceramic capacitance on each side of the device.
