Application Information
OUTPUT CURRENT DERATING FOR T
Due to the limited switch current, the LM2825 cannot supply the full one ampere output current over the entire input and output
voltage range. Figure 8 shows the typical available output current for any input and output voltage combination. This applies for
all output voltage versions.
OUTPUT CURRENT DERATING FOR T
At high these high ambient temperatures, the LM2825 cannot supply the full one ampere over the entire input and output voltage
range. This is due to thermal reasons and Figure 9 shows the typical available output current for any input and output voltage
combination. This applies for all output voltage versions.
