the reference manual "SLUSDY3 – DECEMBER 2023" refers to EN_VREG_TEMP_COMP twice, inside Table 8-25 and Table 8-39.
But they both are just a reference, can…
Hello Ben,
Thanks for being patient with this.
From our testing, a lower resistance is better and a capacitance of 8nF to 20nF works well for the circuit.
Also, it looks like the power path function of your circuit is working well. Let me know if you…
