The TLS805B1SJV is a linear voltage regulator featuring wide input voltage range, low drop out voltage and ultra low quiescent current. With an input voltage range of 2.75V to 42V and ultra low quiescent of only 5μA the regulators are perfectly suitable for automotive or any other supply systems connected permanently to the battery. The TLS805B1SJV is available in adjustable output voltage version with an accuracy of 2 % and output current capability up to 50mA. It is stable with only a small ceramic capacitor of 1μF at the output. The device can be switched on and off by the Enable feature leading to a current consumption of less than 1μA. With extended operating range down to 2.75V, TLS805B1SJV is also suitable to supply automotive systems operating during cranking condition. TLS805B1SJV includes internal protection features like output current limitation and over-temperature shutdown.
