Product details

PSRR and noise rejection at 1 kHz

The TCR4DG12,LF: PSRR is specified at 70 dB at 1 kHz, meaning the regulator attenuates upstream ripple by a factor of roughly 3,160 at that frequency — relevant for cleaning a switching converter's output before feeding a sensitive analog rail. The single regulator output is positive and fixed, with an enable pin for sequencing; protection covers over-current, over-temperature, and short-circuit events.

Package and rework consideration

Housed in a 4-XFBGA, CSPBGA package (supplier device package 4-WCSPE, 0.65 x 0.65 mm), this is a tiny wafer-level chip-scale part — the 4-ball footprint is essentially the die size, so the board land pattern is critical and the part is sensitive to rework thermal profiles.

ROHS3 compliant, with no additional compliance documentation (UL, REACH, IEC) listed in the record.
