Applications Information
Output Voltage Setting
The MAX15006C/MAX15007C provide an adjustable
output voltage from 1.8V to 10V and do not operate in a
preset output voltage mode. Connect an external resis-
tive divider from OUT to FB to GND as shown in Figure
4 to set the desired output voltage. V OUT is calculated
as follows:
? R1 ?
?
? R2 ?
where V FB = 1.23V and a 5 μA minimum current is
required in the external divider for stability.
Available Output Current Calculation
The MAX15006/MAX15007 provide up to 50mA of contin-
uous output current. The input voltage range extends to
40V. Package power dissipation limits the amount of out-
put current available for a given input/output voltage and
ambient temperature. Figure 5 shows the maximum
allowable power dissipation for these devices to keep the
junction temperature below +150°C. Figure 5 assumes
that the exposed metal pad of the MAX15006/MAX15007
is soldered to 1in 2 of PCB copper.
For the SO-EP package:

? ?
After determining the allowable package dissipation,
calculate the maximum allowable output current, with-
out exceeding the +150°C junction temperature, using
the following formula:
P D
V IN ? V OUT
The above equations do not include the negligible
power dissipation from self-heating due to the IC
ground current.
Example 1 (TDFN Package):
T A = +125°C
V IN = 26V
V OUT = 3.3V
Calculate the maximum allowable package dissipation
at the given temperature as follows:
Use Figure 5 to determine the allowable package dissi-
pation for a given ambient temperature. Alternately, use
the following formulas to calculate the allowable pack-
