Automotive Ultra Low Quiescent Current Linear Voltage Regulator TLS810A1LD V33
Application Circuit

The TLS810A1 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 5 µA, the regulator is perfectly
suitable for automotive or any other supply systems connected permanently to the battery.
The TLS810A1LDV33 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 TLS810A1 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
TLS810A1 also suitable to supply automotive systems that need to operate during cranking condition.
