Automotive Low Dropout (LDO), Ultra Low Quiescent Current Linear Voltage
Regulator OPTIREG™ TLS810D1EJ V33

The TLS810D1EJ V33 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 TLS810D1EJ V33 is the fixed 3.3 V output version with an
accuracy of 2 % and output current capability up to 100 mA. The new regulation concept implemented
in TLS810D1EJ V33 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
TLS810D1EJ V33 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.
