Part Number: TPS51285B Tool/software: HI,
in my schematic, the vo1 is left floating. then VR working frequency is around 1.4mhz during heavy loading.
could you help to explain the phenomenon?
in addition, need help to list all funcitons of vo1 pin…
Part Number: TPS51285B Tool/software: We are using TPS51285B regulator in one of our customer reference boards in which we had inadvertently shorted the Open Drain PGOOD pin to 3.3V supply, instead of using pull-up resistor to 3.3V. Would this cause an…
Part Number: TPS51285B Tool/software: Hi Team,
Test to see the 5V LDO fluctuate when 5Vout fluctuate, can you help to explain this? Is there power in transfer here?
Please help to double check attached SCH, thanks!

The TPS51285BRUKR output voltage drops on pin 13 (VREG5) at -5°C. Any suggestions?
By the way, the input power on the front end of the TPS51285BRUKR doesn't drop.
The yellow wire is pin 14 (VO1), and the…
Part Number: TPS51285B Dear Team,
TPS51285B: AS SAME input 12v, output is 5v and 3.3v, Ripple current of cap could reduce to as below?
Many Thanks,
