Automotive Low Dropout (LDO) Linear Voltage Regulator OPTIREG™ TLS850F0TA V33

The TLS850F0TAV33 is a high performance very low dropout linear voltage regulator for 3.3 V supply
in a PGTO263-7 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 TLS850F0TAV33 provides an output voltage accuracy of 2 % and a maximum output current up
to 500 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 80 mV. The operating range starts already at input voltages of only 3 V
(extended operating range). This makes the TLS850F0TAV33 also suitable to supply automotive systems
that need to operate during cranking condition.
