Product details

What this LDO brings to a low-power rail

Its quiescent current is 300 nA.

PSRR and noise rejection in context

With 55 dB of power-supply rejection ratio at 1 kHz, this LDO attenuates ripple from a switching pre-regulator or a noisy digital rail. The protection suite covers over-current, over-temperature, and under-voltage lockout.

The part comes in a 4-X2SON package measuring 1 mm × 1 mm (supplier device package 4-X2SON). The exposed pad underneath must be soldered to the PCB ground plane for thermal relief.

If your line needs cut-tape or a smaller quantity for prototyping, the 'DGN' suffix variants cover those options.

Frequently asked questions

What is the quiescent current of TPS7A0325DQNR?

The quiescent current is 300 nA, which is the standby current drawn by the regulator itself with no load. This is the key spec for battery-powered designs where every microamp of idle drain affects run time.

Is TPS7A0325DQNR obsolete or end-of-life?

No — the part is listed as Active with no end-of-life notice. It is current-production and suitable for new designs.
