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. ## Package and mounting 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. ## Lifecycle and sourcing posture The TPS7A0325DQNR is listed as Active with ROHS3 compliance. There is no end-of-life notice, no last-time-buy window, and no announced successor — this part is current-production and suitable for new designs. If your line needs cut-tape or a smaller quantity for prototyping, the 'DGN' suffix variants cover those options.","metaTitle":"TPS7A0325DQNR LDO Regulator, 2.5V Fixed, 200mA, 300nA Iq","metaDescription":"TI TPS7A0325DQNR ultra-low-Iq LDO: 2.5V fixed output, 200mA, 300nA quiescent, 55dB PSRR at 1kHz, 4-X2SON (1x1mm).
