Pinout
The TLF80511EJ V33 is a 5-pin voltage regulator with the following functions:
1. Input (VIN) – Power supply input (typically 3.3V).
2. Ground (GND) – Reference ground.
3. Enable (EN) – Controls regulator operation (active high).
4. Output (VOUT) – Regulated 3.3V output.
5. Power Good (PG) – Open-drain output indicating stable voltage.
It provides low-dropout (LDO) regulation, overcurrent/thermal protection, and a power-good signal for system monitoring.
