Pinout
1. IN: Input voltage pin. This pin receives the unregulated input voltage that the LDO will regulate.
2. GND: Ground pin. This is the common ground for the regulator and is used as a reference point for the output voltage.
3. NR/FB (Noise Reduction/Feedback): This pin can be used for noise reduction by connecting an external capacitor to ground, improving the power supply rejection ratio (PSRR) and transient response. It can also function as a feedback pin in adjustable versions.
4. OUT: Output voltage pin. This pin provides the regulated output voltage.
5. EN (Enable): Enable pin. It is used to enable or disable the regulator. Pulling this pin high enables the regulator, while pulling it low disables it, reducing power consumption.
The TPS79718DCKR is specifically designed to provide a 1.8V output with low quiescent current, making it suitable for battery-operated devices.
