Pinout
The MAX845EUA-T is a voltage regulator with a pin count of 8. It functions primarily as a low-dropout (LDO) linear regulator designed to provide stable output voltage with a low input-to-output voltage differential.
The pin functions are as follows:
1. Input (VIN): Supplies the input voltage to the regulator.
2. Ground (GND): Common ground connection.
3. Output (VOUT): Delivers the regulated output voltage.
4. Feedback (FB): Used for voltage feedback to maintain output regulation.
5. Enable (EN): Activates or deactivates the regulator; logic high enables it.
6. Compensation (COMP): Provides compensation for stability.
7. Noise Bypass (BP): Reduces noise on the output.
8. Adjust (ADJ): Allows for adjustment of the output voltage.
This device is ideal for powering sensitive analog circuits due to its low noise and high power supply rejection ratio (PSRR).
