The TLT807B0 is a monolithic integrated low dropout adjustable voltage regulator with an enable feature in a small surface mounted package for the harsh environment of automotive applications. The 70mA regulator has an adjustable output voltage and is available in a TSDSO-14 package.

The wide input voltage range and the low quiescent current make it perfectly suitable for supply systems connected permanently to the battery. The over-voltage protection feature allows for the device to increase safety in trucks, commercial vehicles, etc. With a 58V load dump capability, the device is perfectly suited to supply loads in standby mode in 24V automotive applications.

The TLT807B0EPV has an integrated enable function and can be switched on and off via the enable pin. The current consumption in OFF mode is limited to 1.5μA. The device is stable with a small 1μF output capacitor.

The device also includes internal protection features such as output current limitation and over-temperature shutdown.
