Part Number: LMZ31503 In the datasheet, there's a note that indicates PWRGD "is in a defined state once VIN is greater than 1.0V" (page 24) . We're using PWRGD to monitor the status of the output voltage by connecting this signal to a pull-up resistor…
Part Number: LMZ31503 Other Parts Discussed in Thread: LMZ31506 Please let me know about internal inductor value for LMZ31503.
By the way, is LMZ31503 internal inductor value not same as LMZ31506?
Best regards,
Satoshi
Part Number: LMZ31503 Other Parts Discussed in Thread: LMZ31710 Hi team,
The maximum output voltage of the LMZ31503 is 5.5V.
Can I use it at 5.7V?
Or can the output voltage be increased in the same way as the SNVA749?
Best Regards,
Part Number: LMZ31503 Per section 9.7 on sheet 18 of the datasheet, the recommended pull-up resistor value is between 10K and 100K to a voltage source that is 5.5V or less. We're trying to use the PWRGD signal to turn on a status LED and noticed that…

Part Number: LMZ31503 Hi Team,
I'm working with a customer using 3x LMZ31503 to power the 1V,1.8V,3.3V rails on a Xilinx XC7A50t FPGA. All seemed to be working on power up, but on power down the input to the FPGA on all three rails were damaged.
