TLE7274-2D

Infineon Technologies · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

TLE7274-2D from Infineon Technologies, in a TO-252. 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 Regulator input supply. Nominal operating range 5.5 V to 42 V (abs. max -0.3 V to 45 V). Must be blocked to ground directly at the IC with a ceramic capacitor. Typically connected permanently to VBAT.
2 GND power_in Device ground reference. Internally connected to the heat slug/tab; connect the tab to GND and to the PCB heatsink area for thermal dissipation (RthJC ~6 K/W).
3 Q power_out Regulated 5.0 V ±2% output, up to 300 mA (typ. dropout 250 mV @ 200 mA). Must be blocked to ground with a capacitor close to the IC terminals: CQ ≥ 470 nF, ESR ≤ 10 Ω at 10 kHz. Output-current limit min 301 mA; internal sink circuitry keeps VQ ≤ 5.5 V under reverse-current conditions.
TAB GND power_in Heat slug / exposed tab of the PG-TO252-3 package. Internally connected to GND (pin 2); must be soldered to the GND heatsink copper area on the PCB for thermal performance.
