Very High Maximum Input Voltage: 100V
Wide Input Voltage Range: 7V to 100V
Accuracy:
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 100V.

Nominal: 1%
Over Line, Load, and Temperature: 2.5%
The TPS7A4001 is stable with any output
capacitance greater than 4.7µF and any input
capacitance greater than 1µF (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 TPS7A4001
offers an enable pin (EN) compatible with standard
CMOS logic to enable a low-current shutdown mode.

Input Capacitance: ≥ 1µF
The TPS7A4001 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 TJ = –40°C to +125°C.
Output Capacitance: ≥ 4.7µF

Dropout Voltage: 290mV
Built-In Current-Limit and Thermal Shutdown
Protection
In addition, the TPS7A4001 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 very high
and fast voltage transients. These features translate
to simpler and more cost-effective electrical
