Description
Key features of the LP2985IM5-3.3 include a dropout voltage as low as 280mV at full load, which enhances efficiency when the input voltage is close to the output. It's capable of delivering up to 150mA of output current, making it ideal for powering low-power digital and analog devices. The regulator also offers excellent line and load regulation, ensuring consistent performance across a range of operating conditions.
Additionally, the LP2985IM5-3.3 includes several protective features, such as thermal shutdown and current limiting, which safeguard against over-temperature and over-current conditions. Its low noise and high power supply rejection ratio (PSRR) make it suitable for sensitive applications like RF modules and precision analog circuits.
Features
1. Output Voltage: It provides a fixed output voltage of 3.3V.
2. Low Dropout Voltage: Typically around 280 mV at full load, allowing it to operate efficiently even when the input voltage is close to the output voltage.
3. Output Current: Capable of delivering up to 150 mA of output current.
4. Precision Output: Features a tight output voltage tolerance, ensuring precise regulation.
5. Low Quiescent Current: Exhibits very low quiescent current (around 30 µA), making it suitable for battery-powered applications.
6. Stable with Low-ESR Capacitors: Designed to be stable with low equivalent series resistance (ESR) output capacitors, enhancing performance in various applications.
7. Protection Features: Includes thermal shutdown and current limiting to protect against overload conditions.
8. Package Options: Available in a small SOT-23-5 package, which is space-efficient for compact designs.
9. Noise Performance: Low output noise typically around 30 µV RMS, suitable for noise-sensitive applications.
These features make the LP2985IM5-3.3 ideal for portable and battery-powered devices, as well as other applications requiring efficient voltage regulation with low noise and precise output.
Package
Pinout
1. VOUT (Pin 1): Output voltage pin where the regulated 3.3V is available.
2. GND (Pin 2): Ground pin, used as a reference for input and output voltages.
3. SHUTDOWN (Pin 3): A control pin used to enable or disable the regulator. When connected to ground, the regulator is disabled, and when connected to a voltage higher than approximately 2V, the regulator is enabled.
4. VIN (Pin 4): Input voltage pin where the unregulated input voltage is supplied, typically requiring a minimum of around 4V for proper regulation.
5. NC (Pin 5): No Connect pin; generally not connected to any circuitry.
The LP2985IM5-3.3 is commonly used in battery-powered applications due to its low dropout voltage, low quiescent current, and the ability to provide a stable output voltage with minimal external components.
