3 Description
The TPS7A41 device is a very high voltage-tolerant
linear regulator that offers the benefits of a thermally-
enhanced package (MSOP-8), and is able to
withstand continuous DC or transient input voltages
of up to 50 V.
The TPS7A41 is stable with any output capacitance
greater than 4.7 µF and any input capacitance
greater than 1 µF (over temperature and tolerance).
Thus, implementations of this device require minimal
board space because of its miniaturized packaging
(MSOP-8) and a potentially small output capacitor. In
addition, the TPS7A41 offers an enable pin (EN)
compatible with standard CMOS logic, to enable a
low-current shutdown mode.
The TPS7A41 has an internal thermal shutdown and
current limiting to protect the system during fault
conditions. The MSOP-8 packages has an operating
temperature range of T_J = –40°C to 125°C.
In addition, the TPS7A41 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.
