TLV73315PQDBVRQ1

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

TLV73315PQDBVRQ1 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 with a recommended input range of 1.4 V to 5.5 V; a small capacitor is recommended from this pin to ground, and the absolute maximum VIN is 6.0 V.
2 GND power_in Ground pin.
3 EN input Enable pin with a recommended range of 0 V to VIN; drive EN above VEN(HI) to turn the regulator on and below VEN(LO) to put the LDO into shutdown mode.
4 NC unconnected No internal connection.
5 OUT output Regulated output voltage pin with an output range of 1.0 V to 3.3 V; for best transient response, use a small 1-µF ceramic capacitor from this pin to ground.
