CHANGE
9/19/11
FN7713.4 Table 1 on page 1 updated to include more information on Intersil's 1A LDO portfolio.
4/22/11
FN7713.3
In Figure 8 on page 7, corrected label from “VOUT (50V/DIV)." to “VOUT (50mV/DIV)."
In “DC Output Voltage Accuracy” on page 4, corrected the MAX value from -1.8 to +1.8.
2/1/11
FN7713.2
1. page 1, paragraph 2, "The programmable current limiting improves system reliability of applications"
changed to "The programmable current limiting improves system reliability of end applications."
2. page 1, Features, "Programmable Soft-starting" changed to "Programmable Soft-Start"
3. Made subbing consistent throughout document.
4. page 3, EPAD Description “directly to GND plane is optional." Changed to "directly to GND plane is required
for thermal considerations. See "Power Dissipation and Thermals" on page 9 for more details."
5. page 5, Removed Notes in Electrical Spec Table, which read :"Minimum capacitor of 10µF X5R/X7R on VIN
and VOUT required for stability." and "If the current limit for in-rush current is acceptable in application, do
not use this feature. Used only when large bulk capacitance required on VOUT for application."
