Hi TI-team

I saw "TAS2505 Application Reference Guide".

There is a description of ”Reserved. Don't write any value other than Reset Value. ” on the ”Page 1 / Register 2: LDO Control Register - 0x01 / 0x0” on page 70.

However, in ”# LDO output programmed as 1.8V and Level shifters powered up. (P1, R2, D5-D4=00, D3=0)" of P.51, “W 30 02 0” is written to register.

Is there no problem ?

Hi, Hayashi-san,

There should be a typo in the description that you mentioned. You should always write '1' in bit D2 of page 1 / register 2. Writing a '0' shouldn't cause an issue, but in order to ensure the best performance of the LDO, I strongly recommend to write '1' as stated in the registers map.

Please let me know if you have additional questions or comments on this.

Best regards,
Luis Fernando Rodríguez S.
