TL1963A-25DCQR

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

TL1963A-25DCQR 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 Driving SHDN high (above 2 V, VIH max 20 V) enables the device and driving it low (below 0.25 V) disables it; if unused it must be tied to VIN, and the pin has a weak internal pull-down so it disables the device when open.
2 IN power_in Input supply pin; for the old-chip TL1963A-xx the input must be at least VOUT + VDO and no more than 20 V, and reverse-current protection applies when OUT is held above IN.
3 GND power_in Ground pin, which must be connected to the exposed thermal pad on the PCB.
4 OUT power_out Regulator output that delivers up to 1.5 A and requires a capacitor of at least 10 µF with ESR of 3 Ω or less from OUT to ground for stability, placed as close to the pin as possible.
5 SENSE/ADJ input For the fixed-voltage TL1963A-25 this SENSE pin is the error-amplifier input and must be connected to OUT for proper operation, with the SENSE bias current specified as ISENSE in the electrical characteristics.
6 GND power_in Second ground pin, which is tied to the same ground net as pin 3 and the exposed thermal pad.
