TCR2LE18

TOSHIBA · Global Sourcing Parts · SOT-553

TCR2LE18 from TOSHIBA, in a SOT-553. 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 (0.8 to 3.6 V fixed; 1.8 V for TCR2LE18) delivering up to 200 mA, with a 0.1 μF ceramic capacitor recommended and auto-discharge when off.
2 GND power_in Ground reference for the regulator.
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 NC unconnected No internal connection.
5 VIN power_in Input supply, 1.5 to 5.5 V operating (6.0 V absolute maximum), with a 0.1 μF ceramic capacitor recommended.
