Product details

2.8V fixed rail, 300 mA capacity — dropout and PSRR drive the fit

The Toshiba TCR3DF28,LM(CT is a single-output positive LDO regulator delivering a fixed 2.8 V output at up to 300 mA. It comes in a surface-mount SOT-753 package, five pins, with an Enable control pin.

Dropout voltage at full load — the headroom number

Maximum dropout is specified at 0.27 V when sourcing the full 300 mA.

Quiescent current and protection for always-on designs

Quiescent current is 65 µA typical, max supply current 78 µA — a reasonable standby budget for battery-powered equipment that keeps the regulator enabled continuously. Built-in over-current and over-temperature protection cover fault conditions without external clamp diodes.

Package and footprint — SC-74A / SOT-753

The package is a five-pin surface-mount SOT-753. Supplier device package code is SMV.

Frequently asked questions

Is TCR3DF28 RoHS compliant?

Yes, it is listed as ROHS3 Compliant. No additional exemption declarations are needed for standard lead-free assembly.

Is TCR3DF28 compatible with SOT-753 footprint?

Yes — the package / case is SC-74A, SOT-753, and the supplier device package is SMV. The SOT-753 land pattern is the correct footprint for this part.

What is the PSRR of TCR3DF28?

PSRR is specified at 70 dB at 1 kHz. This is a solid figure for a small LDO — it provides meaningful ripple rejection on a 2.8 V rail feeding sensitive analog or RF circuitry, though it is not the highest in the TCR3DF family.
