Recommended parts
GRM188B11A105KA61B(MURATA)
Type
Ceramics capacitor
Connect an input bypass capacitor Cin between VBAT and GND pin and an output capacitor Cout 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 the parts not listed above are used, the equivalent parts must be used.
