●Description:
●The TLS850B0TBV33 is a high performance, very low dropout linear voltage regulator for 3.3 V supply in a PGTO263-
●5 package.
●The input voltage range of 3 V to 40 V and a very low quiescent current of 20 μA make it the perfect match for
●automotive or other supply systems connected to the battery permanently.
●The new loop concept combines fast regulation and very high stability while requiring only one small ceramic
●capacitor of 1 μF at the output. Below an output current of 100 mA the typical dropout voltage of 100mV is
●very low. The operating range starts at an input voltage of only 3 V (extended operating range). This makes the
●TLS850B0TBV33 suitable for automotive systems that need to operate during cranking condition.
●The device can be switched on and off by the Enable feature.
●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.
●Summary of Features:
● Wide input voltage range from 3.0 V to 40 V
● Fixed output voltage 3.3 V
