Product details

PSRR and noise-sensitive rail performance

The TPS730285DBVT: With 68dB of power-supply rejection at 100Hz, this LDO attenuates low-frequency ripple from upstream switching converters or rectified mains by a factor of roughly 2500 — enough to keep a 10mVpp input ripple below 4µVpp at the output. The 250µA quiescent current (Iq) means the regulator's own draw is modest for always-on rails in battery-powered equipment; the enable pin (active-high) lets the system shut down the output entirely when the load is idle.

Frequently asked questions

What is the PSRR of the TPS730285DBVT?

The power-supply rejection ratio is 68dB at 100Hz, which effectively attenuates low-frequency ripple from upstream converters.

What compliance documentation does Texas Instruments provide for TPS730285DBVT?

The part is ROHS3 compliant.
