OPTIREG™ linear TLS820D2ELVSE

Low dropout linear voltage regulator

The device can be switched on and off by the enable feature.

The output voltage of the TLS820D2ELVSE can be selected between 5 V and 3.3 V by connecting the SEL pin to

VQ or GND. When the SEL pin is connected to VQ, the regulator’s output is set to 5 V; when the SEL pin is

connected to GND, the regulator’s output is set to 3.3 V.

The reset feature supervises the output voltage, including undervoltage reset, delayed reset at power-on and

an adjustable lower reset threshold.

Internal protection features such as output current limitation and overtemperature shutdown, protect the

device from immediate damage caused by failure such as output shorted to GND, overcurrent or

overtemperature conditions.

External components

An input capacitor CI is recommended to compensate for line influences. The output capacitor CQ is necessary

for the stability of the regulating circuit. The TLS820D2ELVSE is designed to be stable with low ESR ceramic

capacitors.
