REVISION
14
Converted to new template
Pg 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"
Ordering Info table, remove ISL80102IR15Z and ISL80103IR15Z.
Note 3 below the ordering info table, removed '1.5V'. So it will read "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 3 as follows:
-Corrected Pin 6 from SS to IRSET
-Removed Note 12 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 per ASYD
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."
to "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 9."
-Added “RPD is the on resistance of the pull down MOSFET, M8. RPD is 300Ohms typically.”
Added "Phase Boost Capacitor (CPB)" section on page 13.
In “Typical Operating Performance” on page 11, revised figure "PSRR vs VIN" which had 3 curves with "Spectral
Noise Density vs Frequency" which has one curve.
Added "FIGURE 32. LOAD TRANSIENT 0A TO 3A, COUT = 10µF CERAMIC, NO CPB (ADJ VERSION)" and "FIGURE
33. LOAD TRANSIENT 1A TO 3A, COUT = 10µF CERAMIC, CPB = 1500pF (ADJ VERSION)"
Initial Release.
