Product details

PSRR profile and noise-sensitive loads

PSRR is specified at 66 dB at 100 Hz, rolling off to 22 dB at 100 kHz. That 100 Hz figure matters for rectified mains ripple rejection; the roll-off above audio frequencies means the regulator handles line-frequency noise well but expects the downstream load to manage switching-regulator hash above 100 kHz. For an analog front-end or precision reference supply, pair this LDO with a post-filter if the switching converter runs above a few hundred kilohertz.

ROHS3 compliant.

Frequently asked questions

Is TPS73534DRBT 3.3V or 3.4V output?

Fixed 3.4V output, not 3.3V. If your design calls for a 3.3V rail, the TPS73533 is the 3.3V fixed-output sibling in the same pin-compatible family.

Is TPS73534DRBT equivalent to TPS73533?

Pin-compatible and same package, but output voltage differs: TPS73534DRBT is fixed 3.4V, TPS73533 is fixed 3.3V. They are not drop-in equivalents unless the load tolerates the 100 mV difference.
