Infineon Technologies · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

TLE42642GHTSA2 from Infineon Technologies, in a SOT-223-4. 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 I power_in Input voltage (operating range 5.5 V to 45 V); block to ground directly with a ceramic capacitor.
2 GND power_in Ground.
3 Q power_out 5-V regulated output; block to ground with a capacitor CQ of at least 10 µF and ESR of at most 4 Ω.
4 GND power_in Ground (datasheet uses pin 4 as the reference for junction-to-pin thermal resistance Rthj-p).
