TPS7A4001: TPS7A4001 negative power supply

Part Number: TPS7A4001
Other Parts Discussed in Thread: LM137, LM337-N


I want to make -85V to -80V with LDO.

For example, is it possible with TPS7A4001?

  • Hi ,

    TPS7A4001 is designed, characterized, and tested as a positive voltage regulator. LM137 and LM337-N are adjustable 3-terminal negative voltage regulators. Since these negative regulators do not have a GND pin, the only limitation is that the Vin to Vout differential must not exceed 40 V in order to remain within the specified operating region. Since your differential is 5 V, these regulators should be good candidates for your application.

    Very Respectfully,
    Ryan
