Packaged in a 4-WCSP (0.79x0.79mm), it is designed for space-constrained applications where a clean, regulated 1.2V rail is needed — typical for core supplies in low-power MCUs, RF transceivers, or sensor modules operating from a 5.5V max input. Dropout voltage is specified at 0.8V max at 100mA load, meaning the input must stay above 2.0V to maintain regulation at that current. In a battery-powered design with a 3.6V Li-ion cell, that leaves comfortable margin even as the cell sags under load. PSRR starts at 85dB at 1kHz and rolls to 50dB at 100kHz — useful for rejecting switching-regulator ripple or digital noise coupling onto the supply. If your load draws spikes above 200mA, the over-current and thermal-shutdown protections will fold back the output; the inrush-current protection handles start-up surges. ## Package reality: WLCSP-4 assembly considerations The 4-WCSP (0.79x0.79mm) package is a wafer-level chip-scale device with solder bumps on the bottom. No exposed thermal pad — all heat dissipation goes through the bumps and PCB copper. The supplier device package code 4-WCSP (0.79x0.79) means the die is essentially the package; board-level reliability depends on solder-joint geometry and underfill if the product sees thermal cycling. Trace the date-code back to Toshiba's authorized chain: the WLCSP marking is laser-etched, and counterfeit re-marking on such a small package is rare but not impossible — the laser etch is a fingerprint. ROHS3 compliance is confirmed.","metaTitle":"Toshiba TCR2DG12,LF LDO Regulator, 1.2V Fixed Output, 200mA","metaDescription":"Toshiba TCR2DG12,LF linear regulator: fixed 1.2V output, 200mA, dropout 0.8V max at 100mA, PSRR 85dB~50dB (1kHz~100kHz).
