Package
The TLV73311PDBVR is a low-dropout (LDO) linear regulator from Texas Instruments. It comes in a SOT-23-5 package type, which is a small-outline transistor package with five pins. This package is commonly used for compact and surface-mounted electronic components.
Pinout
The TLV73311PDBVR is a low-dropout (LDO) voltage regulator made by Texas Instruments. It is housed in a SOT-23-5 package, meaning it has 5 pins. Here is a brief overview of its pin functions:
1. IN (Pin 1): This is the input pin where the voltage to be regulated is applied.
2. GND (Pin 2): This pin serves as the ground connection for the device.
3. EN (Pin 3): The enable pin is used to turn the LDO on or off. When a high voltage is applied, the regulator is enabled, and when low, it is disabled.
4. NC (Pin 4): This is a no-connect pin and is typically not internally connected to the device circuitry.
5. OUT (Pin 5): This is the output pin where the regulated voltage is supplied.
The TLV73311PDBVR offers features such as low quiescent current, low dropout voltage, and fast transient response, making it suitable for portable and battery-powered applications.
