Pinout
The LT1963EQ#PBF is a low dropout (LDO) linear regulator manufactured by Analog Devices, originally from Linear Technology. It typically comes in a 5-pin DD-Pak or TO-220 package. The pin functions are as follows:
1. Input (VIN): The input pin receives the voltage that needs to be regulated. It should be decoupled with a capacitor to ground.
2. Output (VOUT): This pin provides the regulated output voltage. Connect an output capacitor to stabilize the output.
3. Adjust (ADJ): This pin is used to set the output voltage. An external resistor divider is connected to this pin to adjust the output voltage as needed.
4. Ground (GND): This pin is the ground reference for the regulator and should be connected to the system ground.
5. Shutdown (SHDN): An active-low input that allows the regulator to be turned off to save power when not needed.
The LT1963 series is valued for its low dropout voltage, high output current capability, and excellent transient response, making it suitable for a variety of power management applications.
