Linear & Switching Voltage Regulators

The TPS74501PQWDRBRQ1 is a low-dropout (LDO) linear 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 TPS74501PQWDRBRQ1 is a low-dropout linear 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 180mV at maximum load, which makes it suitable for use in battery-powered applications where low power consumption is critical.

Features:

1. Low dropout voltage: The TPS74501PQWDRBRQ1 has a very low dropout voltage of 180mV at maximum load, which allows it to maintain a stable output voltage even when the input voltage is close to the output voltage.
2. High PSRR: The regulator has a high power supply rejection ratio (PSRR) of 80dB at 1kHz, which minimizes the impact of input voltage noise on the output voltage.
3. Low quiescent current: The TPS74501PQWDRBRQ1 has a low quiescent current of 5.5µA, which helps to minimize power consumption in battery-powered applications.
4. Small package size: The regulator is available in a compact QFN package, which makes it suitable for use in space-constrained applications.
5. Wide operating temperature range: The TPS74501PQWDRBRQ1 can operate over a wide temperature range of -40°C to +125°C, making it suitable for use in harsh environments.

Applications:

The TPS74501PQWDRBRQ1 is suitable for a wide range of applications, including:

1. Portable devices: The low dropout voltage and low quiescent current make it ideal for use in battery-powered portable devices such as smartphones, tablets, and wearables.
2. IoT devices: The small package size and low power consumption make it suitable for use in Internet of Things (IoT) devices that require a stable voltage supply.
3. Automotive applications: The wide operating temperature range and high PSRR make it suitable for use in automotive applications where stable voltage regulation is critical.
4. Industrial control systems: The TPS74501PQWDRBRQ1 can be used in industrial control systems to provide a stable voltage supply to sensitive components such as microcontrollers and sensors.

In summary, the TPS74501PQWDRBRQ1 is a low-dropout linear voltage regulator with a low quiescent current, high PSRR, and small package size, making it suitable for a wide range of applications where stable voltage regulation is critical.
