Overview

Description

The LP5900SD-3.3 is a low-dropout (LDO) voltage regulator designed to provide a stable output voltage of 3.3V. It features high power supply rejection, low noise, and a compact package, making it suitable for a variety of applications, including portable devices and battery-powered systems. With a typical dropout voltage of around 300mV at full load, the LP5900SD-3.3 efficiently regulates voltage even when the input voltage is close to the output voltage.
Key features include a wide input voltage range, low quiescent current, and thermal shutdown protection, ensuring reliable operation under varying conditions. The LDO is compatible with ceramic capacitors, enhancing its performance in noise-sensitive applications. Its small footprint and ease of use make it ideal for space-constrained designs, ensuring stable power delivery for microcontrollers, sensors, and RF devices. Overall, the LP5900SD-3.3 is an excellent choice for engineers seeking a reliable and efficient voltage regulation solution.

Features

The LP5900SD-3.3 is a low-dropout (LDO) linear voltage regulator designed to provide a stable output voltage of 3.3V. Key features include:
1. Low Dropout Voltage: Ensures efficient operation with a dropout voltage typically around 300 mV at full load.
2. High Output Current: Capable of supplying up to 200 mA of output current.
3. Power Supply Rejection Ratio (PSRR): High PSRR of over 70 dB helps minimize variations in the output voltage due to fluctuations in the input voltage.
4. Low Quiescent Current: Consumes typically only 40 µA, enhancing battery life in portable applications.
5. Temperature Range: Operates over a wide temperature range from -40°C to +125°C.
6. Overcurrent Protection: Built-in overcurrent protection safeguards against excessive load conditions.
7. Thermal Shutdown: Integrated thermal shutdown feature prevents overheating.
The LP5900SD-3.3 is ideal for battery-powered devices, RF applications, and applications requiring a stable, low-noise power supply.

Package

The LP5900SD-3.3 is available in a small 5-pin SOT-23 package type.

Pinout

The LP5900SD-3.3 is a low-dropout (LDO) voltage regulator with a pin count of 5. The pins and their functions are as follows:
1. Input (Vin): This pin connects to the input voltage supply, typically higher than the output voltage (3.3V in this case).
2. Ground (GND): This pin is connected to the system ground.
3. Output (Vout): This pin provides the regulated output voltage of 3.3V.
4. Enable (EN): This pin is used to enable or disable the regulator; pulling it high turns the device on, while pulling it low turns it off.
5. Bypass (BP): This pin is used to connect a capacitor for noise bypassing, improving output stability and performance.
The LP5900SD-3.3 is known for its low noise, high PSRR, and efficient performance in powering various electronic devices.
