The TPS7A4001DGNT is a 50mA Low-dropout Linear Regulator that is able to withstand continuous DC or transient input voltages of up to 100V. The TPS7A4001 device is stable with any output capacitance greater than 4.7µF and any input capacitance greater than 1µF (over-temperature and tolerance). In addition, the device offers an enable pin (EN) compatible with standard CMOS logic to enable a low-current shutdown mode. The TPS7A4001 has an internal thermal shutdown and current limiting to protect the system during fault conditions. It is ideal for generating a low-voltage supply from intermediate voltage rails in telecom and industrial applications, not only can it 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.
