TPS77030DBVR  

Linear & Switching Voltage Regulators

The TPS77030DBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It is designed to provide a stable and reliable voltage output for a wide range of applications.

Description:

The TPS77030DBVR is a low-dropout linear voltage regulator that operates from an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 3.3V. It is available in a small SOT23 package, making it suitable for space-constrained applications.

Features:

1. Low dropout voltage: The TPS77030DBVR has a low dropout voltage of 300mV at a 1A load, ensuring efficient power supply even under heavy load conditions.
2. High PSRR: The regulator has a high power supply rejection ratio (PSRR) of 80dB at 1kHz, which minimizes the impact of input voltage fluctuations on the output voltage.
3. Low quiescent current: The quiescent current of the TPS77030DBVR is only 5μA, making it suitable for battery-powered applications.
4. Enable function: The regulator features an enable function, allowing the user to turn off the regulator when not needed to save power.
5. Overcurrent protection: The TPS77030DBVR has an overcurrent protection feature that limits the output current to a safe level, preventing damage to the regulator or connected components.
