TLS820D2ELVSEXUMA2

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. 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 V₀ or GND. When the SEL pin is connected to V₀, 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.
