TPS79516DCQR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6

TPS79516DCQR from Texas Instruments, in a SOT-223-6. 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 EN input Enable input, active high and compatible with standard and low-voltage TTL-CMOS levels; drive it low to put the regulator in shutdown, or tie it to IN if shutdown is not needed.
2 IN power_in Input supply to the regulator; recommended VIN is 2.7 V to 5.5 V for the older chip and 2.7 V to 6.0 V for the newer chip.
3 GND power_in Regulator ground pin.
4 OUT power_out Regulator output; a ceramic output capacitor of at least 1 µF from OUT to GND is required for stability.
5 NR/NC passive On the older chip (fixed-voltage versions only) this is the noise-reduction pin, where an external bypass capacitor not exceeding 0.1 µF lowers output noise; on the newer chip this pin is not internally connected (N/C).
6 GND power_in Tab/heat-spreader, electrically connected to GND; solder it to a large ground copper area for thermal performance.
