Product Validation according to AEC-Q100/101 Description The OPTIREG Linear TLS820B2ELVSE is a linear voltage regulator with high performance, very low dropout linear 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 A, 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 F 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 TLS820B2ELVSE suitable for automotive systems that need to operate during cranking condition. The device can be switched on and off by the enable feature.

When the SEL pin is connected to V , the regulators output is set to 5 V when the SEL pin is Q Q connected to GND, the regulators output is set to 3.3 V. Internal protection features such as output current limitation and overtemperature shutdown, protect the device from immediate damage caused by failures such as output shorted to GND, overcurrent or overtemperature conditions. External components An input capacitor C is recommended to compensate for line influences. The output capacitor C is necessary I Q for the stability of the regulating circuit. The TLS820B2ELVSE is designed to be stable with low ESR ceramic capacitors. Type Package Marking TLS820B2ELVSE PG-SSOP-14 820B2VSE Data Sheet 2 Rev. 1.1 2018-09-17
