Présentation
Description
Its dropout voltage is typically around 70 mV at a 250 mA load, which enhances efficiency by minimizing power loss. The TPS73233DBVR supports a wide input voltage range, typically from 1.7V to 5.5V. The device is available in a small SOT-23-5 package, making it ideal for space-constrained designs. Additionally, it offers fast transient response and precise output voltage regulation, which are crucial for applications like portable electronics, RF components, and precision analog circuits.
Equivalent
1. Microchip MCP1825S-3302E/DB: Offers similar features with a 3.3V output voltage and low dropout.
2. Analog Devices ADP3338AKCZ-3.3-R7: Provides comparable performance in voltage regulation and noise.
3. ON Semiconductor NCP1117ST33T3G: Another LDO with a 3.3V output suitable for similar applications.
Ensure to check datasheets for specific performance and compatibility with your application.
Features
1. Low Dropout Voltage: With a dropout voltage of typically 30mV at light loads and 85mV at 250mA, it efficiently regulates voltage even with minimal input-to-output voltage difference.
2. Ultra-Low Noise: It features an output noise of only 30 µVrms, making it suitable for noise-sensitive applications.
3. High PSRR: Provides high power supply rejection ratio, which is critical for maintaining stable output in noisy environments.
4. Low Quiescent Current: Consumes minimal current (around 45 µA), contributing to energy efficiency.
5. Output Current: Capable of delivering up to 250 mA of continuous output current.
6. Thermal Protection: Includes thermal shutdown and current limit protection to prevent damage due to overcurrent or overheating.
7. Small Package: Available in a compact SOT-23-5 package, it is suitable for space-constrained applications.
These features make the TPS73233DBVR ideal for use in portable and battery-powered devices, RF applications, and other systems requiring efficient, low-noise voltage regulation.
Pinout
1. IN (Pin 1): Input voltage pin where the supply voltage is connected.
2. GND (Pin 2): Ground pin, which acts as a reference point for the LDO.
3. EN (Pin 3): Enable pin used to turn the regulator on or off. The device is enabled when this pin is high.
4. NR (Pin 4): Noise reduction pin used for connecting an external capacitor to reduce output noise.
5. OUT (Pin 5): Output voltage pin where the regulated voltage is provided.
The TPS73233 provides a fixed output voltage of 3.3V and is designed for applications requiring low noise, high precision, and low dropout voltage.
