Automotive Low Dropout (LDO), Ultra Low Quiescent Current Linear Voltage
Regulator OPTIREG™ TLS810D1LD V50
The TLS810D1LD V50 is a linear voltage regulator featuring wide input voltage range, low drop out voltage
and ultra low quiescent current.
With an input voltage range of 2.75 V to 42 V and ultra low quiescent of only 9 µA, the regulator is perfectly
suitable for automotive or any other supply systems connected permanently to the battery.
The TLS810D1LD V50 is the fixed 5 V output version with an accuracy of 2 % and output current capability
up to 100 mA. The new regulation concept implemented in TLS810D1 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 TLS810D1LD V50 also suitable to supply automotive systems that need to operate during
cranking condition. 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, over-current and over-temperature.
