Product brief TLS835/TLS820 Ultra-low current consumption linear voltage regulator family The TLS835/TLS820 is a family of linear voltage regulators that incorporates features such Key features as wide input voltage range with a best in class combination of low dropout voltage and ultra-low quiescent current. The TLS835 and TLS820 have an output current of 350 mA and Enable and reset 200 mA respectively and are available in the SSOP-14 package. With a wide input voltage Output voltage options: range of 3 V up to 40 V and the ultra-low quiescent current, these products are perfectly ADJ or Selectable (3.3 V or 5 V) suitable for supply systems connected permanently to the battery and for cranking applica- Maximum output current tions. The family offers various options of feature set and output voltage. TLS835: 350 mA TLS820: 200 mA Products in this high performance linear regulator family incorporating the enable feature Current consumption: 20 A typically can be switched on and off using this feature. The current consumption of the device in Available in SSOP-14 package off mode is less than 1 A. The output voltage is supervised by the reset feature, including undervoltage reset and delayed reset release at power-on. The device also includes inter- nal protection features such as output current limitation and overtemperature shutdown. Benefits With this family a brand new feature of a Selectable Output Voltage is being introduced into the automotive linear regulator portfolio. The selectable variant can be configured to Excellent transient robustness either a 5 V or a 3.3 V output by connecting the SEL pin either to output (Q) or to ground smaller input capacitors hence (GND) giving customers even more flexibility in their applications. lower input filtering costs Functional input voltage range starts Applications at 3 V and very low dropout voltage Applications with direct battery connection suitable for cranking Automotive general ECUs Stable with 1 F output capacitor Dashboard, cluster, Infotainment PCB space and cost savings Body control modules Ultra-low quiescent current and current consumption power saving for battery Application schematic I Q C C I Q Current Temperature Battery limitation shutdown line 1 EN RO Enable Sense 0 www.infineon.com/voltage -regulator MicrocontrollerProduct brief TLS835/TLS820 Ultra-low current consumption linear voltage regulator family Family overview Key features Key benefits LV124 Extended input Suitable for very low cranking severe range cranking (stop and start) 3.0 V Ultra-low Energy efficiency: quiescent 22 A Save battery resources for current ECUs in stand-by mode 85C Excellent line Design for harsh ISO2a transient automotive environment pulse Product table Product OPN Output current I Quiescent current I Enable Reset Output voltage Package out q feature feature mA A V TLS835D2ELVSE TLS835D2ELVSEXUMA1 350 25 Yes Yes Selectable 5 V or 3.3 V SSOP-14 TLS835B2ELV TLS835B2ELVXUMA1 350 22 Yes No Adjustable SSOP-14 TLS835B2ELVSE TLS835B2ELVSEXUMA1 350 22 Yes No Selectable 5 V or 3.3 V SSOP-14 TLS820B2ELVSE TLS820B2ELVSEXUMA1 200 20 Yes No Selectable 5 V or 3.3 V SSOP-14 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.
