Infineon Technologies · Linear Voltage Regulators (LDO) · TO-263-7

TLE4267G from Infineon Technologies, in a TO-263-7. 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; block to ground directly at the IC by a ceramic capacitor, with operating range 5.5 V to 40 V.
2 E2 input Inhibit; device is turned on by a High signal on this pin, with an internal pull-down resistor of 100 kΩ.
3 RO output Reset Output; open-collector output internally connected to the output via a resistor of 30 kΩ.
4 GND power_in Ground; connected to rear of chip.
5 D passive Reset Delay; connect via capacitor to GND to set the reset delay time.
6 E6 bidirectional Hold; see Table 6 for function, this input is connected to output voltage via a pull-up resistor of 50 kΩ.
7 Q power_out 5 V Output; block to GND with 22 μF capacitor, ESR < 3 Ω.
8 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
