TCR3UF30A

TOSHIBA LM · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

TCR3UF30A from TOSHIBA LM, in a SOT-25. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply voltage. Operating range 1.5 to 5.5 V (absolute max 6.0 V). A ceramic input capacitor CIN >= 1 µF should be connected between VIN and GND close to the pin.
2 GND power_in Ground reference for the regulator. Return path for input and output currents.
3 CONTROL input Enable/on-off control input. VCT(ON) >= 1.0 V enables the regulator; VCT(OFF) <= 0.4 V disables it. Range 0 to VIN (abs max VIN+0.3, <=6.0 V). Internally pulled down to GND (ICT ~ 0.1 µA typ.), so the pin may be left low for shutdown.
4 NC unconnected No internal connection. Leave floating or tie to a copper pour as convenient for layout.
5 VOUT power_out Regulated output voltage, 3.0 V fixed for the TCR3UF30A variant. Drives up to 300 mA (typical dropout 206 mV at 3.3 V/300 mA). Requires ceramic output capacitor COUT >= 1 µF. Auto-discharge FET (RSD ~ 7 Ω typ.) pulls VOUT to GND when CONTROL is low (A-suffix parts only).

CAD (KiCad official)

  • Symbol: TCR3UF30A
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-25 (KiCad packages3D, STEP)
  • 3D model files: tcr3uf30a-etched.step / tcr3uf30a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tcr3uf30a.step / tcr3uf30a.glb are the bare package body.
