The TPS7A4001-EP device is a very high voltage-tolerant linear regulator that offers the
benefits of a thermally-enhanced package (HVSSOP) and is able to withstand continuous DC or
transient input voltages of up to 100 V.
The TPS7A4001-EP device is stable with any output capacitance greater than 4.7 µF and any
input capacitance greater than 1 µF (over temperature and tolerance). Therefore, implementations of
this device require minimal board space because of its miniaturized packaging (HVSSOP) and a
potentially small output capacitor. In addition, the TPS7A4001-EP device offers an enable pin (EN)
compatible with standard CMOS logic to enable a low-current shutdown mode.
The TPS7A4001-EP device has an internal thermal shutdown and current limiting to protect
the system during fault conditions. The TPS7A4001-EP device has an operating temperature range of
TJ = -55°C to 125°C.
In addition, the TPS7A4001-EP device 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
