**Description** The LP2980-N is a 50-mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications. Using an optimized VIP (Vertically Integrated PNP) process, the LP2980-N delivers unequaled performance in all specifications critical to battery-powered designs: Dropout voltage: Typically 120 mV at 50-mA load, and 7 mV at 1-mA load. Ground pin current: Typically 375 µA at 50-mA load, and 80 µA at 1-mA load. Sleep mode: Less than 1-µA quiescent current when ON/OFF pin is pulled low. Minimum part count: Requires only a 1-µF capacitor on the regulator output. Precision output: 0.5% tolerance output voltages available (A grade). **Features** 2.1-V to 16-V Input Voltage Range 5-V, 4.7-V, 3.3-V, 3-V, and 2.5-V Output Versions Ultra-Low-Dropout Voltage Output Voltage Accuracy 0.5% (A Grade) Ensured 50-mA Output Current Requires Only 1-µF External Capacitance
