TLV77018PDBVR

Texas Instruments · IC · SOT-23-5

TLV77018PDBVR 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 (1.4V to 5.5V); use the nominal 1µF or larger capacitor from IN to ground, placed as close to the IN and GND pins as possible.
2 GND power_in Common ground.
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 output.
4 N/C unconnected No internal electrical connection; connect to GND for improved thermal performance.
5 OUT power_out Regulated output voltage; requires a low-ESR capacitor (0.47µF to 40µF effective) to ground for stability, with an internal pulldown resistor discharging the output when disabled.
