TPS72501KTTR

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

TPS72501KTTR 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 ENABLE input Enable input; the absolute maximum voltage range on EN is -0.3 V to VI + 0.3 V.
2 IN power_in Input supply voltage; recommended VI is 1.8 V to 6 V and the absolute maximum range is -0.3 V to 7 V.
3 GND power_in Ground terminal; the tab is also GND on the KTT package.
4 OUT power_out Regulated output voltage; continuous output current is 0 to 1 A and the absolute maximum voltage on OUT is 6 V.
5 RESET/FB bidirectional On the TPS72501 this is the feedback input of the adjustable regulator (reference 1.220 V); on the fixed options it is an open-drain active-low RESET output that asserts when the output falls more than 5% below nominal and needs a pullup resistor.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
