TPS7A6550QKVURQ1

TPS7A6550QKVURQ1 is a low-power, low-dropout (LDO) voltage regulator manufactured by Texas Instruments. This device is designed to provide stable and reliable voltage regulation in a wide range of applications.

Description:

The TPS7A6550QKVURQ1 is a low-dropout linear voltage regulator with an input voltage range of 2.5V to 5.5V and an output voltage range of 1.2V to 3.3V. It has a very low dropout voltage of 250mV at maximum load, making it suitable for battery-powered applications where input voltage can be close to the output voltage. The device is available in a small QFN package (1x1mm), making it ideal for space-constrained applications.

Features:

1. Low dropout voltage: 250mV at maximum load
2. Wide input voltage range: 2.5V to 5.5V
3. Wide output voltage range: 1.2V to 3.3V
4. Low quiescent current: 2.5µA (typical)
5. High PSRR (Power Supply Reject Ratio): 80dB at 1kHz
6. Small package size: 1x1mm QFN
7. Enable/Disable control
8. Overcurrent protection
9. Thermal shutdown protection
10. Reverse current protection
