TLE42744GSV33

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

TLE42744GSV33 from Infineon, in a SOT-223-4. 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 I power_in Input supply pin. Operating input voltage 4.7 V to 40 V (absolute max -42 V to +45 V). Should be bypassed to GND directly at the IC with a ceramic capacitor (100 nF to 470 nF typical), optionally with a 10-470 uF bulk electrolytic for high-energy transients.
2 GND power_in Ground reference. Internally connected to the heat slug; should tie to the PCB ground plane / heatsink copper.
3 Q power_out Regulated 3.3 V ±2% output (VQ = 3.23 V / 3.30 V / 3.37 V). Supplies up to 400 mA continuous with typical dropout of 250 mV at 250 mA. Requires an output capacitor for stability: CQ >= 22 uF with ESR <= 3 Ω at 10 kHz, placed close to the Q and GND pins.
4 HEAT_SLUG passive Exposed thermal tab / heat slug on the underside of the SOT-223-4 package. Internally connected to GND. Must be soldered to a GND copper pour that also serves as the heatsink area to meet thermal requirements (RthJC ~17 K/W, RthJA ~54 K/W on 2s2p FR4).
