The TPS7A4101 is a very high voltage-tolerant linear regulator that offers the benefits of a thermally-enhanced package (HVSSOP-8), and is able to withstand continuous DC or transient input voltages of up to 50 V.

The TPS7A4101 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 (HVSSOP-8) and a potentially small output capacitor. In addition, the TPS7A4101 offers an enable pin (EN) compatible with standard CMOS logic, to enable a low-current shutdown mode.

The TPS7A4101 has an internal thermal shutdown and current limiting to protect the system during fault conditions. The HVSSOP-8 packages has an operating temperature range of TJ = –40°C to 125°C.

In addition, the TPS7A4101 is ideal for generating a low-voltage supply from intermediate voltage rails in telecom and industrial applications; not only can the device supply a well-regulated voltage rail, but the device 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.
