TPS73633DBVR

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

TPS73633DBVR 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 Input supply pin. Operating range 1.7 V to 5.5 V (absolute max -0.3 V to 6.0 V). Provides the unregulated input voltage to the LDO pass element.
2 GND power_in Ground reference for the device. Ground pin current is typically 400 uA at 10 mA load and 800 uA at 400 mA load.
3 EN input Enable input. Driving EN high (>=1.7 V) turns on the regulator; driving EN low (<=0.5 V) puts the device in shutdown (Iq < 1 uA). Absolute max -0.3 V to 6.0 V. Can be tied to IN if not used.
4 NR passive Noise-reduction pin (fixed-voltage versions only, including the TPS73633). Connecting an external capacitor (typ 0.01 uF) from NR to GND bypasses noise generated by the internal bandgap, reducing output noise to 30 uVRMS (10 Hz-100 kHz) with a 10 uF output cap. Absolute max -0.3 V to 6.0 V.
5 OUT power_out Regulated output of the LDO. Fixed 3.3 V nominal on the TPS73633; up to 400 mA continuous output current. Stable with any value/type of output capacitor, including none.
