TCR3DM33

TOSHIBA · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4(1x1)

TCR3DM33 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 (3.3 V fixed for TCR3DM33), up to 300 mA, with a 1.0 μF ceramic output capacitor recommended.
2 GND power_in Ground pin; the center electrode should be connected to GND or left open.
3 CONTROL input On/off control input: high (1.0 to 5.5 V) turns the output on, low (0 to 0.4 V) or open turns it off, with an internal pull-down to GND.
4 VIN power_in Input supply voltage, 1.75 to 5.5 V operating (6.0 V absolute maximum), with a 1.0 μF ceramic input capacitor recommended.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
