LP2980IM5X-3.8/NOPB - Texas Instruments

The LP2980IM5X-3.8/NOPB is a high-performance, micro-power voltage regulator from Texas Instruments, designed to deliver a fixed output voltage of 3.8V with up to 50 mA of load current. This regulator is part of the LP2980 series, which is known for its low dropout voltage and low quiescent current, making it an excellent choice for battery-powered applications where power efficiency is critical.

This device comes in a compact SOT-23 package, which is ideal for space-constrained applications. It is characterized by its high accuracy, with a specified output voltage tolerance of ±0.5% at room temperature and ±1% over the full temperature range of -40°C to 125°C. This precision ensures reliable operation for sensitive electronic circuits.

One of the key features of the LP2980IM5X-3.8/NOPB is its low dropout voltage, typically just 280 mV at full load, which allows for better regulation and efficiency even when the supply voltage is close to the output voltage. The low quiescent current of typically 30 µA (850 µA during peak load) further enhances its suitability for portable applications, as it helps to prolong battery life.

The regulator also includes a variety of safety and convenience features. It has built-in current limiting and thermal shutdown to protect against fault conditions. The device also includes a low-battery warning indicator, which signals when the input voltage falls below a preset threshold, allowing for preventive maintenance before power failure occurs.

With its impressive combination of features, the LP2980IM5X-3.8/NOPB is a robust power management solution for a wide range of applications, including PDAs, mobile phones, wireless devices, and other portable consumer electronics. Its lead-free and RoHS-compliant design also makes it an environmentally friendly choice for manufacturers looking to create sustainable products.
