Package
The LT3080EMS8E is packaged in an MSOP-8 (Mini Small Outline Package) with exposed pad for improved thermal performance.
Pinout
The LT3080EMS8E is a low dropout linear regulator developed by Linear Technology, now part of Analog Devices. It comes in an 8-lead MSOP package. Here is a brief overview of its pin functions:
1. IN (Pin 1): Input voltage supply. The voltage is supplied to the regulator through this pin.
2. OUT (Pin 2): Regulated output voltage. The voltage regulated by the device is outputted through this pin.
3. SET (Pin 3): The SET pin is used to set the output voltage in conjunction with a resistor connected between this pin and the output.
4. SHDN (Pin 4): Shutdown. A high or open level enables the device, while a low level disables it.
5. GND (Pin 5): Ground. This is the ground reference for the device.
6. NC (Pin 6): No connection. This pin is typically left unconnected.
7. NC (Pin 7): No connection. Similar to Pin 6, usually left unconnected.
8. NC (Pin 8): No connection. As with Pin 6 and Pin 7, this is left unconnected.
These connections make the LT3080EMS8E versatile for various applications requiring precise voltage regulation.
