Texas Instruments  TPS7A4101DGNT

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

The TPS7A4101 is stable with any output capacitance greater than 4.7 µF and any inputcapacitance greater than 1 µF (over temperature and tolerance). Thus, implementations of thisdevice require minimal board space because of its miniaturized packaging (HVSSOP-8) and apotentially small output capacitor. In addition, the TPS7A4101 offers an enable pin (EN) compatiblewith standard CMOS logic, to enable a low-current shutdown mode.

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

In addition, the TPS7A4101 is ideal for generating a low-voltage supply from intermediatevoltage rails in telecom and industrial applications; not only can the device supply awell-regulated voltage rail, but the device can also withstand and maintain regulation during veryhigh and fast voltage transients. These features translate to simpler and more cost-effectiveelectrical surge-protection circuitry for a wide range of applications.
