Pinout
The TPS78433QDBVRQ1 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments, specifically designed for automotive applications. It typically comes in a 5-pin SOT-23 package, known for its compact size and suitability for space-constrained applications.
Here’s a brief overview of the pin functions:
1. VIN: Input voltage pin where the unregulated voltage is supplied.
2. GND: Ground pin, which is the reference point for the circuit.
3. VOUT: Regulated output voltage pin that provides the constant 3.3V output.
4. EN (Enable): A pin used to enable or disable the regulator. A high logic level on this pin turns the regulator on, while a low logic level turns it off.
5. NC (No Connect): A pin that is not internally connected. It should be left unconnected or connected to ground for mechanical stability.
This LDO is well-suited for applications requiring low quiescent current and low dropout voltage, providing stable operation in environments with varying input voltages.
