Test Circuit
Application Information
PROGRAMMING OUTPUT VOLTAGE
(Selecting R1 and R2 as shown in
Figure 3)
The LM2825 is available in two adjustable output versions.
The LM2825-ADJ has been optimized for output voltages
between 1.23V and 8V, while the LM2825H-ADJ covers the
output voltage range of 7V to 15V. Both adjustable versions
are set in the following way.
Select a value for R1 between 240
Ω and 1.5 kΩ. The lower
resistor values minimize noise pickup at the sensitive adjust
pin. (For lowest temperature coefficient and the best stability
with time, use 1% metal film resistors.)
Select R2 with the following equation.
When programming V
OUT, keep in mind that VIN must be
greater than V
OUT + 2V for proper operation.
OPTIONAL EXTERNAL COMPONENTS
SOFT-START CAPACITOR
C
SS: A capacitor on this pin provides the regulator with a
Soft-start feature (slow start-up). The current drawn from the
source starts out at a low average level with narrow pulses,
and ramps up in a controlled manner as the pulses expand
to their steady-state width. This reduces the startup current
considerably, and delays and slows down the output voltage
rise time.
