Hi,

For our internal project we are using TPS77833D LDO. Kindly review the attached schematics and let me know the comments if any.

Hello,

I think the schematic looks fine. Please take care ensure that C_OUT (C20) has an ESR in the range 50mΩ ≤ R_ESR ≤ 1.5Ω. Thanks!

Regards,

Hello Shreehari,

May I know the reason for having the inductor at the Input of the LDO and what its value is? The inductor could cause voltage spikes during load transients and start-up. Increasing the value of the associated capacitor (C19) to 10uF e.g. would help reduce the magnitude of the spikes. Thanks!

Regards,

Srikanth
