Electrical Characteristics
(Notes 2, 6) (Continued)
Note 6:
All room temperature limits are 100% tested or guaranteed through statistical analysis. All limits at temperature extremes are guaranteed by correlation
using standard Statistical Quality Control methods (SQC). All limits are used to calculate Average Outgoing Quality Level (AOQL). Typical numbers are not
guaranteed, but do represent the most likely norm.
Note 7:
The current source is connected internally between V
IN
and V
IOUT
. The voltage across the current source, [V
IN
V
IOUT
], is referred to as headroom voltage.
For the current source to regulate properly, a minimum headroom voltage must be present across it. Minimum required headroom voltage is proportional to the
current flowing through the current source, as dictated by this equation: V
HR-MIN
= 300mV x (I
OUT
÷ 20mA).
Note 8:
An internal 500k
pull-down resistor is connected between the EN and GND pins.
