Outputs 0.8V and 1.0V trimmable down to 0.6V using the
on-board voltage reference (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)

* All specifications 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.
