3 Description
The TPS7A4201 device is a 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 28 V.
The TPS7A4201 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 (MSOP-8) and a potentially
small output capacitor. In addition, the TPS7A4201
offers an enable pin (EN) compatible with standard
CMOS logic to enable a low-current shutdown mode.
The TPS7A4201 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 TPS7A4201 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 fast voltage
transients. These features translate to simpler and
more cost-effective electrical surge-protection circuitry
for a wide range of applications.
