TPS7A4501KTTR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-5

TPS7A4501KTTR from Texas Instruments, in a TO-263-5. 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 control input; pull low to disable output, leave high or open-collector with pullup resistor to enable; typically 3 μA pullup current required.
2 IN power_in Power supply input; requires 1 μF to 10 μF ceramic bypass capacitor if more than six inches from main input filter capacitor; absolute maximum ±20 V.
3 GND power_in Ground reference; exposed thermal pad must be soldered to PCB for rated thermal performance.
4 OUT power_out Regulated power supply output; minimum 10 μF ceramic output capacitor required to prevent oscillations.
5 ADJ input Error amplifier adjustment input (adjustable version only); internally clamped to ±7 V with 3 μA bias current; 1.21 V to 20 V output voltage range.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
