Automotive Low Dropout (LDO), Ultra Low Quiescent Current Linear
Voltage Regulator OPTIREG™ TLS810D1LD V33

The TLS810D1LD 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 TLS810D1LD 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 TLS810D1LD 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 TLS810D1 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.
