TLV741285PDBVR

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

TLV741285PDBVR 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 input Input pin; the datasheet says to use a small capacitor from this pin to ground.
2 GND power_in Ground pin.
3 EN input Enable pin: driving EN above 0.9 V turns the regulator on, and driving EN below 0.4 V puts it into shutdown mode.
4 NC unconnected No internal connection.
5 OUT output Regulated output voltage pin; for best transient response, use a small 1-µF ceramic capacitor from this pin to ground.
