TLE4276G V50

Infineon Technologies · Linear Voltage Regulators (LDO) · TO-263-5

TLE4276G V50 from Infineon Technologies, in a TO-263-5. 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, to be blocked to ground directly at the IC with a ceramic capacitor; the V50 input range is VQ + 0.5 V to 40 V.
2 INH input Low-active inhibit input; switching the regulator off via this pin reduces the current consumption below 10 µA.
3 GND power_in Ground reference pin for the regulator; the heatsink is also to be connected to GND.
4 N.C. unconnected Not connected for the V50 version; the voltage adjust input VA on pin 4 applies only to the adjustable version.
5 Q power_out Output of the 5.0 V regulator (4.8 V to 5.2 V, up to 400 mA), to be blocked to GND with a capacitor of at least 22 µF with ESR ≤ 3 Ω at 10 kHz.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
