Product brief TLS850B0-family High-performance linear voltage regulator The TLS850B0 is a high-performance, very low dropout linear voltage regulator for 3.3 V and 5.0 V supply in a TO263-5 and TO252-5 package. The input voltage range of 3.0 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 while requiring only one small ceramic capacitor of 1 F at the output. Below an output current of 100 mA the typical dropout voltage of 100 mV is very low. The operating range starts at an input voltage of only 3 V (extended operating range). This makes the TLS850B0 suitable for automotive systems that need to operate during cranking condition. Key features Enable Output voltage accuracy: 2 percent Dropout voltage: 100 mV Current consumption: 20 A Available in TO252 and TO263 package Wide operating temperature range: -40C Tj 150C The device can be switched on and off by the enable feature. Benefits Internal protection features like output current limitation and overtemperature shutdown protect the device from immediate damage.
