TPS79518DCQR

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

TPS79518DCQR 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 pin. Drive high to turn on the regulator. Drive low to place regulator in shutdown mode; if unused, connect to IN.
2 IN power_in Device input supply voltage; recommended operating range 2.7V to 6.0V for new chip (2.7V to 5.5V for old chip).
3 GND power_in Regulator ground connection.
4 OUT power_out Regulated output voltage; 1.8V nominal for TPS79518.
5 NR/NC/FB passive Pin function varies: Old chip fixed version-Noise Reduction (NR) pin for external bypass capacitor to filter bandgap reference noise (0.001µF to 0.1µF); New chip fixed version-No internal Connection (NC); Adjustable versions-Feedback (FB) input for output voltage programming.
6 GND power_in Ground connection and thermal pad; internally connected to GND; connect to large ground plane for thermal management.
