TIDA-00270
電流分載雙 LDO
TIDA-00270
概覽
This power supply topology is capable of sourcing 6A via two LDOs operating in parallel. The solution sources current evenly between the two TPS74401’s, each capable of supplying 3A. This design allows for higher currents to be supplied than is typically possible with a single LDO. It also allows for additional heat syncing not available with an individual LDO.
特點
- Sources up to 6A
- High PSRR to filter ripple
- Low Noise output to provide a clean rail
- Low dropout regulation
- High Accuracy (1% over temperature)
- Soft-start allows for monotonic startup
