1) This parameter defines the minimum input voltage for which the device is powered up and provides the maximum nominal

output current of 300 mA. The output voltage of the adjustable version in this condition depends on the chosen setting of

the external voltage divider as well as on the applied conditions

– thus the device is either regulating its nominal output

voltage or is in tracking mode.The 3.3 V fixed voltage version is by definition in tracking mode for such low input voltages.

2) For the adjustable version of the TLS203B0 the dropout voltage for certain output voltage / load conditions will be restricted

by the minimum input voltage specification.

3) The adjustable version of the TLS203B0 is tested / specified for these conditions with the ADJ pin connected to the Q pin.

4) The operation conditions are limited by the maximum junction temperature. The regulated output voltage specification will

only apply for conditions where the limit of the maximum junction temperature is fulfilled. It will therefore not apply for all

possible combinations of input voltage and output current at a given output voltage. When operating at maximum input

voltage, the output current must be limited for thermal reasons. The same holds true when operating at maximum output

current where the input voltage range must be limited for thermal reasons.

5) To satisfy requirements for minimum input voltage, the TLS203B0 adjustable version is tested and specified for these

conditions with an external resistor divider (two 250 k resistors) for an output voltage of 2.44 V. The external resistors will

add a 5 µA DC load on the output.
