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.
