TCR3DM45

TOSHIBA · Linear Voltage Regulators (LDO) · DFN-4(1x1)

TCR3DM45 from TOSHIBA, in a DFN-4(1x1). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated output voltage pin (4.5 V fixed for TCR3DM45), up to 300 mA, with a 1.0 µF ceramic output capacitor placed close to the pin.
2 GND power_in Ground pin.
3 CONTROL input On/off control input: high (VCT 1.0 to 5.5 V) turns output on, low (0 to 0.4 V) or open turns it off, with an internal pull-down to GND.
4 VIN power_in Supply input voltage pin, 1.75 to 5.5 V operating (6.0 V absolute maximum), with a 1.0 µF ceramic input capacitor.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
