TLS835D2EL VSE

With an input voltage range of 3 V to 40 V and very low quiescent current of only 20 μA, this regulator is perfectly suitable for automotive or other supply systems permanently connected to the battery.
The new loop concept combines fast regulation and very high stability while requiring only one small ceramic capacitor of 1 μF at the output. At output currents below 100 mA the device will have a very low dropout voltage of only 100 mV (for 5 V output voltage) and 120 mV (for 3.3 V output voltage). The operating range starts at an input voltage of only 3 V (extended operating range). This makes the TLS835D2 suitable for automotive systems that need to operate during cranking condition.

The device can be switched on and off by the Enable feature. The output voltage of TLS835D2ELVSE can be selected between 5 V and 3.3 V by connecting the SEL pin to V_Q or GND. When the SEL pin is connected to V_Q, the regulator’s output is set to 5 V; when the SEL pin is connected
to GND, the regulator’s output is set to 3.3 V. The output voltage is supervised by the Reset feature, including Undervoltage Reset, delayed Reset at Power- On and an adjustable lower Reset Threshold. Internal protection features like output current limitation and overtemperature shutdown protect the device from immediate damage due to failures such as output shorted to GND, overcurrent and overtemperature.
