TLS850A4TEV50 BOARD

The OPTIREG™ linear voltage regulator TLS850A4TEV50 demoboard allows for easy lab evaluation of the TLS850A4TEV50. The demoboard is populated with the TLE850A4TEV50 in a PG-TO252-3 (DPAK) package, as well as the standard external components and test points to allow for easy device evaluation.
The OPTIREG™ linear TLS850A4TEV50 is an Infineon high performance regulator with low dropout voltage and ultra low quiescent current. With only 4.3 μA typical quiescent current at light load and an input voltage range of 3.7 V to 40 V the device is perfectly suitable for automotive supply systems or other supply systems that are permanently connected to the battery. The loop concept combines fast regulation and very high stability while requiring only one small ceramic capacitor of 4.7 μF at the output. The operating range starts at an input voltage of 3.7 V (extended operating range). This makes the device suitable for automotive systems that need to operate in cranking condition. Internal protection features, such as output current limitation and overtemperature shutdown, are designed to protect the device from immediate damage caused by failures such as:

• output shorted to GND
• overcurrent condition
• overtemperature condition

The thermally conductive package enables sustained operation despite significant dissipation across the device.

• Automotive supply systems or other supply systems that are connected to the battery permanently
• Automotive systems that need to operate in cranking condition
• General automotive applications
