Automotive Low Dropout (LDO) Linear Voltage Regulator OPTIREG™ TLS820F1EL V50

The TLS820F1ELV50 is a high performance very low dropout linear voltage regulator for 5 V supply
in a PGSSOP-14 package.

With an input voltage range of 3 V to 40 V and very low quiescent of only 40 µA, these regulators are
perfectly suitable for automotive or any other supply systems connected to the battery permanently.
The TLS820F1ELV50 provides an output voltage accuracy of 2 % and a maximum output current up
to 200 mA. The new loop concept combines fast regulation and very good stability while requiring
only one small ceramic capacitor of 1 µF at the output. At currents below 100 mA the device will have
a very low typical dropout voltage of only 70 mV. The operating range starts already at input voltages
of only 3 V (extended operating range). This makes the TLS820F1ELV50 also suitable to supply
automotive systems that need to operate during cranking condition.
