Description

The OPTIREG™ linear TLS820D2ELVSE is a linear voltage regulator with high performance, very low dropout

voltage and very low quiescent current.

With an input voltage range of 3 V to 40 V and very low quiescent current of only 20 µA, this regulator is

perfectly suitable for automotive or other supply systems permanently connected to the battery.

The new loop concept combines fast regulation and very high stability while requiring only one small ceramic

capacitor of 1 µF at the output. At output currents below 100 mA the device has a very low dropout voltage of

only 100 mV (for an output voltage of 5 V) and 120 mV (for an output voltage of 3.3 V). The operating range

starts at an input voltage of only 3 V (extended operating range). This makes the TLS820D2ELVSE suitable for

automotive systems that need to operate during cranking condition.
