Package and board-fit — HRP-5 with exposed tab
The BA25DD0WHFP-TR comes in the HRP-5 package (5 leads plus a tab), with the supplier device package also designated HRP-5.
2A fixed 2.5V rail with 0.7V dropout
This is a single-output, positive fixed 2.5V LDO rated for 2A continuous output current.
55dB PSRR at line frequency and protection set
Power supply rejection ratio is 55dB at 120Hz — this is the line-frequency (full-wave rectified) ripple rejection figure. For a 2.5V rail feeding analog or mixed-signal loads, that 55dB means 120Hz ripple on the input is attenuated by a factor of ~560, keeping the output clean enough for most sensor and ADC supply applications. The quiescent current is 120 µA, which is moderate for a 2A-rated LDO — not an ultra-low-Iq part, but the trade-off buys the 55dB PSRR and the 0.7V dropout. Protection features include over-current, over-temperature, and over-voltage — the regulator shuts down or folds back under fault conditions rather than passing through an unregulated voltage. An Enable control pin is also present for sequencing or shutdown.
Temperature grade and sourcing posture
The lifecycle status is Active, and the part is ROHS3 compliant.
