说明

The TPS7A4001 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 100V.

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.

The TPS7A4001 has an internal thermal shutdown and current limiting to protect the system during fault conditions.
