Package
The TLV74333PDBVR is a part of the TLV743 series of low-dropout linear regulators by Texas Instruments. It comes in a SOT-23-5 package, which is a small outline transistor package with five leads. This package type is compact, making it suitable for small electronic devices and space-constrained applications.
Pinout
The TLV74333PDBVR is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It typically comes in a 5-pin SOT-23 package. Here is a concise description of its pin configuration and functions:
1. Pin 1 (IN): Input Voltage - This pin is connected to the supply voltage. It is where the unregulated input voltage is applied.
2. Pin 2 (GND): Ground - This pin is the ground reference for the circuit, and all voltages are measured with respect to this pin.
3. Pin 3 (EN): Enable - This pin is used to enable or disable the regulator. It must be driven high to turn on the regulator and low to turn it off.
4. Pin 4 (NC): No Connect - This pin is not internally connected and is usually left unconnected or used for mechanical stability.
5. Pin 5 (OUT): Output Voltage - This pin provides the regulated output voltage, which, in this specific part number (TLV74333), is fixed at 3.3V.
The TLV74333 is suitable for applications requiring ultra-low quiescent current and a stable output voltage, particularly in battery-powered devices.
