TL1963ADCQR from Texas Instruments, in a SOT-223-6. 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 | SHDN | input | Active-low shutdown input. Pulling SHDN low forces the regulator into low-power shutdown (output off, quiescent <1 µA). Drive with 5-V logic or open-collector with pullup; typical SHDN pin current is 3 µA. VIH ≥ 2 V, VIL ≤ 0.25 V. Tie to VIN if unused; leaving floating keeps the device off. |
| 2 | IN | power_in | Regulator input supply. Bypass with a 1 µF to 10 µF ceramic capacitor close to the pin. Withstands reverse voltage vs. GND and OUT (reverse-battery protection). Absolute max ±20 V; recommended VIN ≥ VOUT + VDO up to 20 V. |
| 3 | GND | power_in | Device ground. Tied together with pin 6 on the DCQ package. |
| 4 | OUT | power_out | Regulated output supply, up to 1.5 A. Requires a minimum 10 µF ceramic output capacitor for stability; larger values recommended for large transient loads. Dropout ≈ 340 mV at 1.5 A. |
| 5 | SENSE/ADJ | input | Feedback input to the internal error amplifier. On the adjustable TL1963A (this MPN base) this is ADJ: connect a resistor divider from OUT to set VOUT = 1.21 V × (1 + R2/R1) up to 20 V; ADJ is internally clamped to ±7 V and sinks ~3 µA. On fixed variants (-15/-18/-25/-33) the same pin becomes SENSE, tied to OUT at the load (bias ~600 µA at rated IOUT) for Kelvin sensing. |
| 6 | GND | power_in | Device ground / exposed metal tab on SOT-23-6 DCQ. Ties to pin 3; connect to the ground plane for thermal performance. |
