1 Typical continuous output current at 30 V in and 3.3 V out. Actual achievable continuous output current is a function of input and output voltages and is limited by thermal dissipation. See the output current graph on the product page for more information.
2 Input voltage must be higher than the output voltage and is subject to dropout voltage considerations; see the dropout voltage section of product pages for more information.

Notes:

1
Without included optional headers.
2
Operating voltage must be higher than the set output voltage and is subject to dropout voltage considerations; see the dropout voltage graph under the description tab for more information.
3
Output voltage is set by a built-in precision 11-turn potentiometer.
4
Typical maximum continuous output current at 30 V in and 3.3 V out. Actual achievable continuous output current is a function of input and output voltages and is limited by thermal dissipation. See the output current graph under the description tab for more information.
5
To -40 V. Connecting supplies over 40 V in reverse can damage the device.
6
While enabled with no load. The quiescent current is a function of the input voltage, output voltage, and cutoff voltage. It is reduced to under 1 mA at higher input voltages and with correspondingly higher cutoff voltage settings or when the regulator is disabled via the enable pin. See the quiescent current graph under the description tab for more information.
