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

TLV77325PDBVR 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 voltage supply, specified at 1.4 V to 5.5 V in the Recommended Operating Conditions, with a 1 µF nominal input capacitor placed as close to the IN and GND pins as possible.
2 GND power_in Common ground, to which all voltages in the datasheet are referenced.
3 EN input Enable input: a voltage below VEN(LOW) turns the regulator off and discharges the output to GND, and a voltage above VEN(HI) enables the regulated output, with VEN rated 0 V to 5.5 V.
4 N/C unconnected No internal electrical connection; the datasheet recommends connecting this pin to GND for improved thermal performance.
5 OUT output Regulated output voltage that requires a low-ESR capacitor from OUT to ground (0.47 µF to 40 µF effective, ESR up to 100 mΩ), with an internal pulldown that discharges VOUT in shutdown.
