Recommended PCB layout

In PCB design, wire the power supply line in a way that the PCB impedance goes low and provide a bypass capacitor if needed.

Ceramics capacitor

Connect an input bypass capacitor CIN between VBAT/VIN and GND pin and an output capacitor between VOUT and GND

pin in proximity. Place both C1P-C1N and C2P-C2N capacitors in proximity to the chip Furthermore, select a ceramics

capacitor with a sufficient rating for voltage to be applied.

When other than these parts are used, the equivalent parts must be used.
