TPS78001DDCR

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

TPS78001DDCR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Unregulated input supply pin, 2.2 V to 5.5 V recommended (absolute max 6.0 V). Requires a ~1.0-μF ceramic bypass capacitor to GND placed close to the pin to assure stability.
2 GND power_in Device ground return. Tie all ground references (input capacitor, output capacitor, load) to this pin with low-impedance connections for proper operation.
3 EN input Active-high enable input, CMOS logic compatible. Drive above 1.2 V to enable the regulator; drive below 0.4 V to enter shutdown (IGND ≈ 18 nA typ). Input current ≈ 40 nA at VEN = 5.5 V. Do not leave floating.
4 VSET/FB input On the TPS78001 (adjustable version) this pin is the feedback (FB) input to the internal 1.216-V reference amplifier; connect to the OUT resistor-divider tap to program VOUT between 1.22 V and 5.25 V. On fixed dual-output TPS780xx variants the same pin acts as VSET: <0.4 V selects VOUT(HI), >1.2 V selects VOUT(LO). IFB ≈ 10 nA typ.
5 OUT power_out Regulated LDO output, up to 150 mA. Requires a ~1.0-μF ceramic capacitor to GND for stability. Dropout ≈ 200 mV at 150 mA; output accuracy ±3% over line/load/temperature.
