TPS79912DDCR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS79912DDCR from Texas Instruments, in a SOT-23-5. 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 IN power_in Input supply voltage with recommended operating range of 2.7 V to 6.5 V.
2 GND power_in Ground connection; the pad must be tied to GND.
3 EN input Enable input; driving this pin high turns on the regulator, driving this pin low puts the regulator into shutdown mode.
4 NR passive Noise reduction pin for fixed voltage versions only; connecting to external capacitor bypasses noise generated by internal band gap.
5 OUT power_out Regulated output; ceramic capacitor with total capacitance ≥ 2 μF required from this pin to ground for stability.
