Texas Instruments TPS7A4001
The TPS7A4001 device is a very high voltagetolerant linear regulator that offers the benefits of a thermally-enhanced package (HVSSOP), and is able to withstand continuous DC or transient input voltages of up to 100 V. The TPS7A4001 device is stable with any output capacitance greater than 4.7 µF and any input capacitance greater than 1 µF (over temperature and tolerance). The TPS7A4001 device has an internal thermal shutdown and current limiting to protect the system during fault conditions.| Part No. | TPS7A4001 |
