  • LP5912: LP5912-1.2DRVR_Output Load Capacitance

    TI Thinks Resolved
    Part Number: LP5912 Tool/software: Hello, For LDO LP5912-1.2DRVR, the output capacitance mentioned is 10pF (maximum) only as per datasheet. But. the 1.2V output have 40pF load capacitance as per our design. Please confirm whether the LDO supports 40pF…

  • LP5912: LDO without UVLO as supercap charger

    Resolved
    Part Number: LP5912 Tool/software: Hi, I am looking for LDO without UVLO that would (ideally) passthrough the Vin to Vout when Vin < Vmin. Or, at least guarantee monotonic startup (no on-off UVLO oscillations) The purpose of the circuit is to work…

  • LP5912-Q1: Calculate min/max output over lifetime (including temp. change and aging)

    Part Number: LP5912-Q1 Other Parts Discussed in Thread: TPS7A21-Q1 , TPS7A20 Tool/software: Hello, I'm planning to use a LP5912-Q1 (3.3V variant) in a SIL-2 system. For my documentation I need to calculate the absolute min/max output voltage under…

  • LP5912-EP: EN pin developed a low impedance to GND pin

    TI Thinks Resolved
    Part Number: LP5912-EP Tool/software: From one day to the next, the voltage regulator I was using developed a low impedance (16ohms) between pins 4 and 5 on the WSON package. As EN was also tied to the Vin, this caused the supply for the circuit to go…

  • LP5912: Output Voltage Confirmation

    Part Number: LP5912 I'm planning to use the LDO part LP5912-1.8DRVR to generate a 1.8V output using a 2.5V input. From the LP5912 datasheet, I'm able to confirm that we can generate 1.8V using a 2.5V input voltage (VIN = VOUT + 0.5V). However, even though…

  • LP5912: Inrush Current when Cout is 10uF

    TI Thinks Resolved
    Part Number: LP5912 Dear Specialists, My customer has a same type of question. I would be grateful if you could advise. --- (1) In the reference thread, there is a discussion when Isc exceeds 1100mA at Figure 51. of datasheet P.16. There is no clear mention…
