TPS7A4515DCQR

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

TPS7A4515DCQR 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 SHDN puts the regulator into a low-power shutdown state when pulled low, can be driven by 5-V, 3-V or open-collector logic with a pullup, has VIH of 2 V minimum and VIL of 0.25 V maximum, and must be connected to VIN if unused.
2 IN power_in IN supplies power to the device with an input voltage range of VOUT + VDO to 20 V, is designed to withstand reverse voltages with respect to ground and OUT, and benefits from a 1-µF to 10-µF ceramic bypass capacitor when the device is more than six inches from the main input filter.
3 GND power_in Ground reference pin for the regulator; the exposed thermal pad that must be soldered to the PCB for rated thermal performance is specified for the KTT package, not the DCQ package.
4 OUT power_out OUT supplies power to the load and requires a minimum 10-µF ceramic output capacitor to prevent oscillations, with larger capacitors needed for large transient loads.
5 SENSE input SENSE is the error amplifier input for the fixed-voltage TPS7A4515 (1.5 V), should be connected to OUT for optimum regulation with a bias current of 600 µA at the rated output voltage, and can be pulled below ground in dual-supply systems.
6 GND power_in Ground pin, present on the DCQ package only.
