The LP2980 is a 50 mA, fixed output voltage regulator designed to meet the requirements of battery-powered applications.
Using an optimized VIP (vertically integrated PNP) process, the LP2980 delivers unmatched performance in a variety of specifications critical to battery-powered designs:
Voltage difference. Typically a load of 120 mV @ 50 mA, and a load of 7 mV @ 1 mA.
Ground pin current. Typically 375 μ A@ 50 mA load, and 80 μ A@ 1 mA load.
Sleep mode. ON/OFF pins with quiescent currents below 1μA are pulled low.
Minimum part count. Only 1μF of the output capacitance of the external regulator is required.
Precision output. 0.5% tolerance output voltage (Class A).
Available as standard 5.0V, 4.7V, 3.3V, 3.0V and 2.5V versions.
