The TLS805B1LD V50 is a linear voltage regulator featuring wide input voltage range, low dropout voltage and ultra low quiescent current. With an input voltage range of 2.75 V to 42 V and ultra low quiescent of only 5.5 μA, the regulator is perfectly suitable for automotive or any other supply systems connected permanently to the battery. The TLS805B1LD V50 is the fixed 5 V output version with an accuracy of 2% and output current capability up to 50mA. The new regulation concept implemented in TLS805B1LD V50 combines fast regulation and very good stability while requiring only a small ceramic capacitor of 1 μF at the output. The tracking region starts already at input voltages of 2.75 V (extended operating range). This makes the TLS805B1LD 50V also suitable to supply automotive systems that need to operate during cranking conditions. Internal protection features like output current limitation and overtemperature shutdown are implemented to protect the device against immediate damage due to failures like output short circuit to GND, overcurrent and overtemperature. The device can be switched on and off by the Enable feature. When the device is switched off, the current consumption is typically less than 1 μA. Summary of Features Ultra low quiescent current of 5.5 μA Wide input voltage range of 2.75 V to 42 V Output current capacity up to 50 mA Off mode current less than 1 μA Low drop out voltage of typ. 100 mV @ 50 mA Output current limit protection Overtemperature shutdown Enable Available in PG-TSON-10 package Wide temperature range Green Product (RoHS Compliant) AEC Qualified Family Overview For an overview of other available options in this family please click here.
