TPS709A33DBVT

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

TPS709A33DBVT 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 OUT output Regulated output voltage; connect a 2.2-µF or greater ceramic capacitor from this pin to ground to assure stability.
2 GND power_in Ground pin, which is electrically connected to the thermal pad; connect the thermal pad to the GND plane for improved thermal performance.
3 IN input Unregulated input to the device, with a recommended input voltage range of 2.7 V to 30 V.
4 NC unconnected No internal connection.
5 EN input Enable pin: drive high to enable the device and low to enter low current shutdown; it can be left floating to enable the device, and the maximum voltage must remain below 6.5 V.
