TL1963A-25DCYT

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

TL1963A-25DCYT from Texas Instruments, in a SOT-223-4. 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 supply pin; for the new-chip version VIN must be 2.4 V to 20 V, and for the old chip VIN must be at least VOUT + VDO with an absolute maximum of 20 V.
2 GND power_in Ground pin; the exposed thermal pad on the DCY package is also ground and must be soldered to the PCB to achieve the rated thermal performance.
3 OUT power_out Regulator output that requires a capacitor of at least 10 µF with ESR of 3 Ω or less from OUT to GND for stability, placed as close to the pin as possible.
4 GND power_in Ground pin; the exposed thermal pad on the DCY package is also ground and must be soldered to the PCB to achieve the rated thermal performance.
