Product details

Fixed 3.3 V rail from a 5.5 V ceiling

The TCR2DG33,LF is a single-output positive LDO from Toshiba's TCR2DG series, delivering a fixed 3.3 V at up to 200 mA.

Package and placement

Housed in a 4-bump WLCSP (0.79 x 0.79 mm), the part fits into tight portable and wearable layouts where board real estate is at a premium. The surface-mount 4-UFBGA footprint demands a consistent solder-paste stencil aperture — the 0.79 mm body leaves minimal room for passive decoupling between the input and output bumps.

Protection and quiescent draw

Built-in inrush current limiting, over-current protection, and thermal shutdown handle fault conditions without external supervisory circuitry — useful for designs that must survive a shorted load or a hot-plug event without latching up. Quiescent current is 70 µA typical, which keeps the always-on regulator's own draw low in battery-powered applications where the load spends most of its time in a light sleep state.

Lifecycle and compliance

Marked as Active by Toshiba and fully ROHS3 compliant, the TCR2DG33,LF has no announced end-of-life — suitable for both new designs and sustaining production.

Frequently asked questions

What is the closest functional alternative to TCR2DG33,LF?

Within the same TCR2DG series, the TCR2DG12,LF is the closest sibling — identical package (4-WCSP), same 200 mA output and protection set, but with a fixed 1.2 V output instead of 3.3 V. It will not drop in as a direct substitute unless the downstream rail voltage matches.

What compliance documentation does Toshiba provide for TCR2DG33,LF?

The part is ROHS3 compliant per the manufacturer's declaration.
