The LP2980AIM5-3.3 is a fixed-output, low-dropout (LDO) voltage regulator from Texas Instruments (TI), designed specifically to deliver a stable and reliable power supply. This high-performance regulator is capable of sourcing a 50mA load with excellent line and load regulation.
Key Features
- Output Voltage: The device provides a precise 3.3V output, which is ideal for powering sensitive analog and digital circuits.
- Low Dropout: With a dropout voltage typically at 280mV at full load, the LP2980AIM5-3.3 maintains output voltage even when the input supply is very close to the output voltage, enhancing efficiency.
- High Accuracy: Output voltage accuracy is specified at ±3%, ensuring reliable operation for critical applications.
- Low Ground Pin Current: The typical ground pin current of 850µA increases only slightly in dropout, contributing to overall efficiency.
- Stable with Low ESR Capacitors: The device is stable with ceramic capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) than tantalum capacitors.
- Thermal Protection: Built-in thermal shutdown protection safeguards the device and the system under extreme conditions.
- Current Limiting: The internal current limiting feature protects the input source and the LP2980AIM5-3.3 during fault conditions.
