General Description

The LP2980 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 delivers unequaled performance in all specifications critical to battery-powered designs:

Dropout Voltage. Typically 120 mV @ 50 mA load, and 7 mV @ 1 mA load.

Ground Pin Current. Typically 375 μA @ 50 mA load, and 80 μA @ 1 mA load.

Sleep Mode. Less than 1 μA quiescent current when ON/OFF pin is pulled low.

Minimum Part Count. Requires only 1 μF of external capacitance on the regulator output.

Precision Output. 0.5% tolerance output voltages available (A grade).

5.0V, 4.7V, 3.3V, 3.0V and 2.5V versions available as standard products.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
