DescriptionThe LP2967 is a 150 mA, dual fixed-output voltage regulator designed to provide ultra low-dropout and low noise in battery powered applications.
Using an optimized VIP (Vertically Integrated PNP) process, the LP2967 delivers unequalled performance in all specifications critical to battery powered designs:
Dropout Voltage: Typically 240 mV at 150 mA load, and 6 mV at 1 mA load for each output.
Ground Pin Current: Typically 1 mA at 150 mA load, and 200 µA at 1 mA load for each output.
Enhanced Stability: The LP2967 is stable with output capacitor ESR as low as 5 m, which allows the use of ceramic capacitors on the output.
Sleep Mode: Less than 2 µA quiescent current when SD pins are pulled low.
Smallest Possible Size: micro SMD package uses absolute minimum board space.
Precision Output: 1.25% tolerance.
Low Noise: By adding a 100 nF bypass capacitor, output noise can be reduced to 30 µV (typical).
Multiple voltage options, from 1.8V to 5.0V, are available. Consult factory for custom voltages.

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.For more information on Reliability Metrics, please click here.
