Description

The LP3970 is a multi-function, programmable Power Management Unit, designed especially for advanced application processors. The LP3970 is optimized for low power handheld PMU applications and provides 11 low dropout, low noise linear regulators, two DC/DC magnetic buck regulators, a back-up battery charger and 4 GPO's. A high speed serial interface is included to program individual regulator output voltages as well as on/off control.

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.
