TPS7A4518DCQR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6

TPS7A4518DCQR from Texas Instruments, in a SOT-223-6. 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 SHDN input Shutdown input accepting 5V or 3V logic levels with typical 3 μA input current; pull low to disable output or connect to VIN if unused.
2 IN power_in Power supply input requiring 1-10 μF ceramic bypass capacitor if more than six inches from main filter; protected against reverse voltage on both IN and OUT pins.
3 GND power_in Ground reference.
4 OUT power_out Regulated 1.8V output power supply requiring minimum 10 μF ceramic capacitor to prevent oscillations.
5 SENSE input Feedback input to error amplifier with 600 μA bias current at rated output voltage; connect to output for optimal regulation or to load to eliminate PCB trace voltage drops.
6 GND power_in Ground reference for DCQ package.
