TLV743P: PSRR of TLV743P

Part Number: TLV743P

My customer will use TLV743 at Iout=100~150mA.

Are there the data of PSRR at 100mA or 150mA?

Hi Yokota,

You are correct that the load will impact the PSRR; however, equally important is the headroom (Vin - Vout). What is the headroom in your application?

Hi Ryan-san

Thank you for the information.

Vin=5V and Vout=3.3 / 2.5V

Best regards,

Hi Yookota-san,

Thank you for the additional details. While your application conditions have more headroom (Vin - Vout) than shown below, increasing headroom beyond 1 V only has a marginal impact on PSRR. Your application PSRR will be similar to the performance depicted below:
