Pinout
The pin configuration is as follows:
1. Input (VIN) - Connects to the input voltage supply.
2. Ground (GND) - Provides the ground reference for the regulator.
3. Output (VOUT) - Delivers the regulated output voltage (1.5V).
4. Feedback (FB) - Used for voltage feedback and regulation.
5. Enable (EN) - Controls the activation of the regulator; when high, the device is active, and when low, it is disabled.
This IC features low noise, high power supply rejection ratio (PSRR), and low quiescent current, making it ideal for battery-powered and portable devices.
