Pinout
The LT1963AES8-3.3 is a low dropout (LDO) linear voltage regulator. It comes in an 8-pin SO-8 package. Here’s a brief overview of its pin functions:
1. VIN (Pin 1): Input voltage supply pin.
2. GND (Pins 2, 3, 7): Ground pins. These pins should be connected to a low impedance ground plane for optimal performance.
3. VOUT (Pin 4): Output voltage pin. It provides a regulated output of 3.3V.
4. SENSE (Pin 5): The sense pin allows for remote sensing of the output voltage to improve regulation at the load.
5. SHDN (Pin 6): Shutdown pin. A high input enables the regulator, while a low input puts it in a low-power shutdown mode.
8. NC (Pin 8): No connection pin, typically used as a spacer or for mechanical stability.
