CHANGE
Pin Descriptions on page page 3, updated EPAD section From: EPAD at ground potential. Soldering it directly to
GND plane is optional. To: EPAD must be connected to copper plane with as many vias as possible for proper
electrical and optimal thermal performance.
Removed obsolete part numbers: ISL80102IR33Z, ISL80102IR50Z, ISL80103IR33Z, ISL80103IR50Z from
Added evaluation boards to ordering information table on page 2: ISL80103IR50Z and ISL80103EVAL2Z.
Features on page 1: Removed 5 Ld TO220 and 5 Ld TO263.
Input Voltage Requirements on page 12: Removed the sentence “those applications that cannot accommodate
the profile of the TO220/TO263”.
In “Thermal Information” on page 4, corrected θ JA from 48 to 45.
Increased “VEN(HIGH)” minimum limit from 0.4V to 0.616 and added the “VEN(LOW)” spec for clarity on page 5.
Increased “Turn-on Threshold” minimum limit on page 5 from 0.3V to 0.4V.
Updated “Package Outline Drawing” on page 16 as follows:
Removed package outline and included center to center distance between lands on recommended land pattern.
Removed Note 4 "Dimension b applies to the metallized terminal and is measured between 0.18mm and 0.30mm
from the terminal tip." since it is not applicable to this package. Renumbered notes accordingly.
Converted to new template
On page 1 - first paragraph, changed "Fixed output voltage options are available in 1.5V, 1.8V, 2.5V, 3.3V and 5V"
to "Fixed output voltage options are available in 1.8V, 2.5V, 3.3V and 5V"
In “Ordering Information” table on page 2, removed ISL80102IR15Z and ISL80103IR15Z.
In Note 3 on page 2, below the “Ordering Information” table , removed '1.5V', so it reads “The 3.3V and 5V fixed
output voltages will be released in the future. Please contact Intersil Marketing for more details.”
Corrected Features on page 1 as follows:
-Changed bullet "? 185mV Dropout @ 3A, 125mV Dropout @ 2A" to "? Very Low 120mV Dropout at 3A"
-Changed bullet "? 65dB Typical PSRR" to "? 62dB Typical PSRR"
-Deleted 0.5% Initial VOUT Accuracy
Modified Figure 1 and placed as “TYPICAL APPLICATION” on page 1.
Moved Pinout to page 3
In “Block Diagram” on page 2, corrected resistor associated with M5 from R4 to R5
Updated “Block Diagram” on page 2 as follows”
- Added M8 from SS to ground.
Updated Figure 1 on page 1 as follows:
-Corrected Pin 6 from SS to IRSET
-Removed Note 11 callout "Minimum cap on VIN and VOUT required for stability." Added Note "*CSS is optional.
See Note 12 on Page 5." and “** CPB is optional. See “Functional Description” on page 12 for more information.”
Added "The 1.5V, 3.3V and 5V fixed output voltages will be released in the future." to Note 3 on page 2.
In “Thermal Information” on page 4, updated Theta JA from 45 to 48.
In “Soft-Start Operation (Optional)” on page 12:
-Changed "The external capacitor always gets discharged to 0V at start-up of after coming out of a chip disable.
"The external capacitor always gets discharged to ground pin potential at start-up or enabling."
-Changed "The soft-start function effectively limits the amount of in-rush current below the programmed current
limit during start-up or an enable sequence to avoid an overcurrent fault condition." to "The soft-start feature
effectively reduces the in-rush current at power-up or LDO enable until VOUT reaches regulation."
-Added "See Figures 25 through 27 in the “Typical Operating Performance Curves” beginning on page 6."
-Added “RPD is the on resistance of the pull-down MOSFET, M8. RPD is 300 ? typically.”
