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 Key features and 5.0 V supply in a TO263-5 and TO252-5 package. Enable The input voltage range of 3.0 V to 40 V and a very low quiescent current of 20 A make it Output voltage accuracy: 2 percent the perfect match for automotive or other supply systems connected to the battery per- Dropout voltage: 100 mV manently. The new loop concept combines fast regulation and very high stability while Current consumption: 20 A requiring only one small ceramic capacitor of 1 F at the output. Below an output current Available in TO252 and TO263 package of 100 mA the typical dropout voltage of 100 mV is very low. The operating range starts Wide operating temperature range: at an input voltage of only 3 V (extended operating range). This makes the TLS850B0 -40C T 150C j suitable for automotive systems that need to operate during cranking condition. The device can be switched on and off by the enable feature. Benefits Internal protection features like output current limitation and overtemperature shutdown Wide input voltage range protect the device from immediate damage. Robust TO252 and TO263 package Reduces energy consumption, suitable for stand-by operation Application diagram for TLS850B0 for 12 V ECUs Minimized external BOM I Q C C I Q Applications Current Temperature Battery limitation shutdown Load General automotive MCU line power supply EPS, 2 wheeler dashboard, EN Enable instrument cluster Body electronics, HVAC panel, etc. www.infineon.com/voltage -regulator Product brief TLS850B0-family High-performance linear voltage regulator V V In Out IQ Key features Key benefits 340 V 1 F Low drop voltage Suitable for cranking TLS850B0x Microcontroller (~100 mV) (stop and start support from V = 3 V) In EN GND Low current Longer battery lifetime consumption (~20 A) Excellent regulation BOM cost optimized loop stable V Out Products Product name OPN Output current Quiescent current Enable R Output voltage Package thJA I I Out q mA A K/W V TLS850B0TBV33 TLS850B0TBV33ATMA1 500 20 Yes 26 3.3 TO263 TLS850B0TBV50 TLS850B0TBV50ATMA1 500 20 Yes 26 5.0 TO263 TLS850B0TEV33 TLS850B0TEV33ATMA1 500 20 Yes 26 3.3 TO252 TLS850B0TEV50 TLS850B0TEV50ATMA1 500 20 Yes 26 5.0 TO252 Demoboards Product name OPN Description TLS850B0TB50 BOARD TLS850B0TB50BOARDTOBO1 TLS850B0 Demoboard DPAK TO263-5, 5.0 V TLS850B0TB33 BOARD TLS850B0TB33BOARDTOBO1 TLS850B0 Demoboard DPAK TO263-5, 3.3 V TLS850B0TE50 BOARD TLS850B0TE50BOARDTOBO1 TLS850B0 Demoboard DPAK TO252-5, 5.0 V TLS850B0TE33 BOARD TLS850B0TE33BOARDTOBO1 TLS850B0 Demoboard DPAK TO252-5, 3.3 V Published by Please note Additional information Infineon Technologies AG THIS DOCUMENT IS FOR INFORMATION PURPOSES ONLY AND For further information on technologies, our products, the 81726 Munich, Germany ANY INFORMATION GIVEN HEREIN SHALL IN NO EVENT BE application of our products, delivery terms and conditions REGARDED AS A WARRANTY, GUARANTEE OR DESCRIPTION OF and/or prices, please contact your nearest Infineon Technologies 2018 Infineon Technologies AG.
