OPTIREG linear voltage regulator TLS850F3TUVxx demoboard ™ Z8F80607085 1 Introduction Introduction General description The TLS850F3TUV33 and TLS850F3TUV50 are monolithic integrated low drop out voltage regulators for loads up to 500 mA in a PG-TO252-7 package (DPAK). With an input voltage range of 3 V to 42 V and very low quiescent current of only 26 µA, these devices are perfectly suitable for automotive or other supply systems connected to the battery permanently. -

OPTIREG linear voltage regulator TLS850F3TUVxx demoboard ™ Z8F80607085 3 Schematic and layout Layout The PCB uses a four layer standard stack-up. The product can also be soldered to double layer boards. However, four layers offer better thermal characteristics. The configuration on this demoboard is comparable to the 2s2p thermal interface situation. - Page 12 OPTIREG linear voltage regulator TLS850F3TUVxx demoboard ™ Z8F80607085 3 Schematic and layout Figure 6 Bottom layer TLS850F3TUVxx demoboard User manual Rev. 1.0 2024-05-08...
