Panasonic recommends a 4-layer PCB with a solid ground plane and a separate power plane for the input and output. The input and output capacitors should be placed as close as possible to the IC pins, and the PCB should be designed to minimize electromagnetic interference (EMI).
To ensure stability, Panasonic recommends using a minimum output capacitance of 10uF with an ESR of 1Ω or less. Additionally, the output voltage should be decoupled with a 1uF ceramic capacitor and a 10uF electrolytic capacitor in parallel.
While the datasheet specifies an operating temperature range of -40°C to 85°C, Panasonic recommends derating the device for reliable operation above 70°C. The maximum ambient temperature for reliable operation is 70°C, and the device should be derated by 1.5°C/W above this temperature.
Panasonic recommends using a voltage supervisor or a reset IC to monitor the input voltage and reset the device in case of an overvoltage or undervoltage condition. Additionally, a TVS diode can be used to protect the device from voltage spikes and surges.
Panasonic recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. The capacitor should be rated for the maximum input voltage and should be placed as close as possible to the IC pins.
