TPS70939DBVR

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

TPS70939DBVR 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 Unregulated input supply; operating range 2.7 V to 30 V, absolute maximum 32 V.
2 GND power_in Ground reference for the regulator; all voltages are referenced to this pin.
3 EN input Enable pin; drive ≥0.9 V to enable the device, ≤0.4 V to enter shutdown (ISHUTDOWN 150 nA typ at VIN = 2.7 V); pin may be left floating to enable (internally pulled up by 300 nA source); maximum voltage must remain below 6.5 V.
4 NC unconnected No internal connection; leave unconnected.
5 OUT power_out Regulated output voltage; connect a 2.2 µF or greater ceramic capacitor (ESR 0 Ω to 0.2 Ω, max 47 µF) from this pin to GND to assure stability; output current limit minimum 200 mA.
