TLS850B0TBV33 Low dropout linear voltage regulator 1 Overview Features Wide input voltage range from 3.0 V to 40 V Fixed output voltage 3.3 V Output voltage accuracy 2 % Output current capability up to 500 mA Ultra low current consumption, typical 20 A Very low dropout voltage, typical 120 mV at 100 mA Stable with ceramic output capacitor of 1 F Enable Overtemperature shutdown Output current limitation Wide temperature range Green Product (RoHS compliant) Potential applications Automotive or other supply systems that are connected to the battery permanently Automotive supply systems that need to operate in cranking condition Product validation Qualified for Automotive Applications. Product Validation according to AEC-Q100/101 Description The TLS850B0TBV33 is a high performance, very low dropout linear voltage regulator for 3.3 V supply in a PG- TO263-5 package. The input voltage range of 3 V to 40 V and a very low quiescent current of 20 A 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. Below an output current of 100 mA the typical dropout voltage is below 100 mV. The operating range starts at an input voltage of only 3 V (extended Data Sheet 1 Rev. 1.00 www.infineon.com/power 2017-09-12 TLS850B0TBV33 Low dropout linear voltage regulator Overview 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 such as output current limitation and overtemperature shutdown protect the device from immediate damage due to failures such as output shorted to GND, overcurrent and overtemperature. Choosing external components An input capacitor C is recommended to compensate line influences. I The output capacitor C is necessary for the stability of the regulating circuit. TLS850B0TBV33 is designed to Q operate stable with low ESR ceramic capacitors. Type Package Marking TLS850B0TBV33 PG-TO263-5 850B0V33 Data Sheet 2 Rev. 1.00 2017-09-12
