• Manufacturer Part Number: ADP5041
• Description: Micro PMU with 1.2 A Buck, Two 300 mA LDOs, Supervisory, Watchdog and Manual Reset
• Manufacturer: Analog Devices

ADP5041
The reliable operation of the buck regulator and the LDO
regulator can be achieved only if the estimated die junction
temperature of the
Reliability and mean time between failures (MTBF) is highly
