The TPS7A4001-DIE is a very high voltage-tolerant linear regulator that is able to withstand continuous dc or transient input voltages.
The TPS7A4001-DIE offers an enable pin (EN) compatible with standard CMOS logic to enable a low-current shutdown mode.
The TPS7A4001-DIE has an internal thermal shutdown and current limiting to protect the system during fault conditions.
In addition, the TPS7A4001-DIE is ideal for generating a low-voltage supply from intermediate voltage rails in telecom and industrial applications; not only it can supply a well-regulated voltage rail, but it can also withstand and maintain regulation during very high and fast voltage transients. These features translate to simpler and more cost-effective electrical surge-protection circuitry for a wide range of applications, including PoE, bias supply, and LED lighting.
