CHANGE
1. Changed POD L10.3X3 on page 12 to latest revision from 6 to 7. Change POD is 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 metalized 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.
1. “Input Voltage Requirements” on page 7 changed input voltages from “2.2V” to “5V”
1. Page 1: On 3rd paragraphs first sentence “CMOS” changed to “BiCMOS”.
2. Page1: 1st paragraph sentence changed from: “This LDO operates from input voltages of 2.2V to 6V. The
ISL80121-5 has a nominal output voltage of 5V”. T0: “The ISL80121-5 operates from input voltages of 5V
to 6V with a nominal output voltage of 5V”.
3. Page 2: Removed Note in Ordering Information: “The 1.5V, 3.3V and 5V fixed output voltages will be released
in the future. Please contact Intersil Marketing for more details”.
4. Page 4: Recommended Operation Conditions “V In relative to GND changed from 2.2V to 6V to 5V to 6V”
5. Page 4: Recommended Operation Conditions Removed “V out Range line 800mV T0 5V”
Table 1 on page 1 updated to include more information on Intersil's 1A LDO portfolio.
In Figure 8 on page 7, corrected label from “V OUT (50V/DIV)." to “V OUT (50mV/DIV)."
In “DC Output Voltage Accuracy” on page 4, corrected the MAX value from -1.8 to +1.8.
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 V IN
and V OUT 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 V OUT for application.”
6. page 5, Electrical Specifications, PG Pin Characteristics, V out PG Flag Threshold
a.Typical "85" changed to “84” %V out
7. page 9, after Thermal Fault Protection section
a.Added “General Power PAD Design Considerations” section with Figure 14.
8. All PGOOD changed to PG throughout.
Changed Theta Ja from 51C/W to 48C/W.
1.page 1, Features
a."200μVrms Output Noise” changed to “210 μVrms Output Noise”
2.page 1, Typical Applications, right side figure
a.Resize "V OUT " (pin2) and “SENSE” (pin3)
3.page 8, Equation 4
a.Extra parenthesis ")" removed
page 3 Pin Number 8, description, 2nd sentence: “Current limit is 0.75mA...” changed to “Current limit is
0.75A…"
page 4 Electrical Specifications, AC Characteristics, Input Supply Ripple Rejection Test conditions and Typical
values changed from “f = 1kHz, ILOAD = 1A, f = 120Hz, ILOAD = 1A”
TO “f = 1kHz, ILOAD = 1A, f = 1kHz, ILOAD = 100mA”
a. Added “ADJ adjustable voltage version” Pin. Added “fixed voltage version” to “SENSE” pin
2. On page 4: “Ground Pin Current” Test Conditions
a. Replaced "V OUT +0.4V" with "2.2V" on both lines
Initial Release.
