Current Limiting

The EL5106 and EL5306 have no internal current-limiting

circuitry. If the output is shorted, it is possible to exceed the

Absolute Maximum Rating for output current or power

dissipation, potentially resulting in the destruction of the

device.

Power Dissipation

With the high output drive capability of the EL5106 and

EL5306, it is possible to exceed the +125°C Absolute

Maximum junction temperature under certain very high load

about 25

Ω, it is important to calculate the maximum junction

power supply voltages, load conditions, or package type

need to be modified for the EL5106 and EL5306 to remain in

the safe operating area. These parameters are calculated as

shown in Equation 1:

Removed obsolete, leaded devices EL5106IW-T7, EL5106IW-T7A; EL5106IS-T7, EL5106IS-

T13; EL5306IS, EL5306IS-T7, EL5306IS-T13; EL5306IU, EL5306IU-T7, EL5306IU-T13

Corrected Figure references in “Gain Setting” on page 7 (Fig 14 callout was referencing Fig

13; Fig 15 callout was referencing Fig 14; Fig 16 callout was referencing Fig 15) .

Updated pin descriptions to match pin names of EL5306.

Applied Intersil Standards: Updated Pb-free bullet in Features, Updated ordering information

by removing tape and reel column and adding standard reference note and updating note to

match lead finish, updated caution statement to legal's suggested verbiage. Changed date

and Rev'd to 6.

Updated POD MDP0038 toP6.064A - P6.064A replaces 6 Ld SOT-23

(same dimensions, just MDP0038 had both 5 & 6 Ld SOT23s w/dimensions listed in table)

Updated POD MDP0027 to M8.15E - M8.15E replaces MDP0027 8 Ld SOIC (same

dimensions, just MDP0027 had 8, 14, 16, 20, 24, 28 Ld SOICS with dimensions listed in table)

P1, added Note 2 "The part marking is located on the bottom of the part" for SOT-23 package
