TLV1117-33IDCYR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

TLV1117-33IDCYR from Texas Instruments, in a SOT-223-4. 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 GND power_in Ground reference providing current return path for input and output circuits; rated for 800mA output current maximum.
2 VOUT power_out Regulated 3.3V output capable of 0-800mA load current; requires output capacitor with ESR 2-500mΩ and 10µF minimum capacitance for stability.
3 VIN power_in Positive supply input accepting 4.7-15V for TLV1117-33; requires minimum 0.4V dropout voltage at 100mA to 1.2V at 800mA for linear regulation.
4 VOUT power_out Regulated 3.3V output capable of 0-800mA load current; typically paralleled with Pin 2 for improved current distribution and reduced trace impedance.
