FEATURES

„

* All speciﬁ cations are typical at nominal input, full load at 25°C unless otherwise stated.

** Max 10A for 5.0V output.

*** Pull below 0.4V and sink greater than 50 μA or leave open to enable the SIP; pull above 2V (do not exceed 15V) and source greater than 150 μA

to disable the SIP.

**** The output capacitors must meet the max ESR = 100 mΩ requirement over the operating temperature range.

Outputs 0.8V and 1.0V trimmable down to 0.6V using the on-board voltage refer-

ence (option 7 or F, see pg 2 and trimming equations on pg 8). Standard setpoint

accuracy varies from ±1.5% at the low end of the output voltage range, to ±3% at

the high end. (see chart on pg 2) Contact factory for tighter tolerances. See note on

pg 8 for trimming to different voltages.
