3 Description
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 T_J = –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
lighting.
