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.","metaTitle":"Toshiba TCR4DG12,LF LDO, 1.2V Fixed, 420mA, 4-WCSPE","metaDescription":"Active Toshiba TCR4DG12,LF LDO regulator, 1.2V fixed output, 420mA, 70dB PSRR at 1kHz, 4-WCSPE package.
