# TPS72515KTTR

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

TPS72515KTTR 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 datasheet gives the EN voltage range as -0.3 V to VI + 0.3 V in the absolute maximum ratings. |
| 2 | IN | power_in | Input supply voltage; recommended VI is 1.8 V to 6 V and the absolute maximum is -0.3 V to 7 V. |
| 3 | GND | power_in | Ground pin; the datasheet states the tab is also GND on the KTT package. |
| 4 | OUT | power_out | Regulated output voltage; the absolute maximum voltage on OUT is 6 V. |
| 5 | RESET/FB | output | On the fixed-output TPS72515 this terminal is an open-drain active-low RESET output (used with a pullup resistor) that asserts when the output drops more than 5% below nominal, with a typical 50 ms delay; the absolute maximum voltage on RESET is 6 V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
