Package

The LT1764EQ-3.3#TRPBF is a low dropout (LDO) linear regulator packaged in a TO-220 form. The "#TRPBF" suffix indicates that it is tape and reel packaging and is lead-free (RoHS compliant).

Pinout

The LT1764EQ-3.3#TRPBF is a low dropout (LDO) linear regulator. It typically comes in a 5-pin TO-220 package. The pin functions are generally as follows:
1. Input (VIN): This pin receives the input voltage that you want to regulate down to 3.3V.
2. Ground (GND): This is the reference ground pin for the regulator.
3. Output (VOUT): This provides the regulated 3.3V output voltage.
4. Enable (EN): This pin allows the regulator to be turned on or off using a digital signal. Pulling it high typically enables the regulator.
5. Adjustment (ADJ): Although the fixed 3.3V version may not use this pin, in adjustable versions, it allows the output voltage to be set by an external resistor network.
Please refer to the manufacturer's datasheet for detailed information on pin configuration and electrical characteristics to ensure correct application and integration into your design.
