Adjusting the Output Voltage of the ATH15T033
& ATH15T05 Wide-Output Adjust Power Modules
The
V
o
Adjust
control (pin 4) sets the output voltage of
the ATH15T033 and ATH15T05 products. The ad-
justment range of the ATH15T033 (3.3-V input) is from
0.8 V to 2.5 V
1
, and the ATH15T05 (5-V input) from
0.8 V to 3.6 V. The adjustment method requires the addi-
tion of a single external resistor, R
set
, that must be connected
directly between the
V
o
Adjust
and
GND
pins
2
. Table 1-1
gives the preferred value of the external resistor for a num-
ber of standard voltages, along with the actual output
voltage that this resistance value provides.
For other output voltages the value of the required resistor
can either be calculated using the following formula, or
simply selected from the range of values given in Table 1-2.
Figure 1-1 shows the placement of the required resistor.

Adjust Resistor Placement
Notes:
1. Modules that operate from a 3.3-V input bus should
not be adjusted higher than 2.5 V.
2. Use a 0.1 W resistor. The tolerance should be 1 %, with
temperature stability of 100 ppm/°C (or better). Place
the resistor as close to the regulator as possible. Connect
the resistor directly between pins 4 and 7 using dedicated
PCB traces.
3. Never connect capacitors from
V
o
Adjust
to either
GND
or
V
out
. Any capacitance added to the
V
o
Adjust
pin will affect
the stability of the regulator.
