Package

The TPS79618DCQR is packaged in a VQFN (Very Thin Quad Flat No-lead) format, specifically a 16-pin VQFN package.

Pinout

The TPS79618DCQR is a low-dropout (LDO) voltage regulator from Texas Instruments. It features a 5-pin package configuration, specifically the SC70-5.
Pin Count and Functions:
1. Vin (Pin 1): Input voltage supply, where the input voltage is applied.
2. GND (Pin 2): Ground connection.
3. Vout (Pin 3): Output voltage, where the regulated output is taken.
4. NC (Pin 4): No connection; this pin is not internally connected and should be left unconnected.
5. Enable (Pin 5): Enables or disables the regulator; pulling this pin high activates the output.
