TLV74325PDQNR

The TLV74325PDQNR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It is designed to provide a stable output voltage with high efficiency and low noise, making it suitable for a variety of applications, including portable devices, battery-powered equipment, and other electronic systems requiring precise voltage regulation.

Key Features:

1. Output Voltage: The TLV74325 is available in a fixed output voltage version, typically providing 2.5V. This makes it ideal for powering low-voltage digital circuits and components.

2. Input Voltage Range: The device can accept a wide input voltage range, typically from 2.5V to 6.5V, allowing it to be used in various power supply configurations.

3. Low Dropout Voltage: The LDO features a low dropout voltage, which is the minimum difference between the input and output voltage required for the regulator to function properly. This characteristic is crucial for battery-operated devices, as it maximizes the usable battery life.

4. Output Current: The TLV74325 can deliver a maximum output current of up to 250 mA, making it suitable for powering a range of devices without overheating or compromising performance.

5. Quiescent Current: The device boasts a low quiescent current, which is the current consumed by the regulator when it is not supplying load current. This feature is particularly beneficial in battery-powered applications, as it helps extend battery life.

6. Thermal Protection: The TLV74325 includes built-in thermal shutdown protection, which prevents the device from overheating and potentially damaging itself or the connected load.

7. Package Type: The "PDQNR" designation indicates that the device comes in a small, thermally enhanced package (SOT-23-5), which is suitable for space-constrained applications. The compact size allows for easy integration into printed circuit boards (PCBs).

8. Noise Performance: The LDO is designed to provide low output noise, which is essential for sensitive analog and RF applications where power supply noise can affect performance.

9. Stability: The TLV74325 is stable with a wide range of output capacitors, including ceramic capacitors, which are commonly used in modern electronic designs.

Applications:

• Portable electronics
• Battery-powered devices
• RF and analog circuits
• Microcontrollers and DSPs
• Power management systems
