Note 1:
Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications, see Electrical Characteristics.
Note 2:
Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by T
(maximum
junction temperature),
θ
J-A
(junction to ambient thermal resistance) and T
(ambient temperature). The maximum power dissipation at any temperature is:
P
DissMAX
= (T
JMAX
- T
A
) /θ
J-A
up to the value listed in the Absolute Maximum Ratings.
θ
J-A
for SOT23-5 package is 220°C/W, T
JMAX
= 125°C.
Note 3:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin.
Note 4:
Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality
Control.
Note 5:
Typical numbers are at 25°C and represent the most likely parametric norm.
Note 6:
Temperature coefficient is measured by the "Box" method; i.e., the maximum
Δ
V
REF
is divided by the maximum
Δ
T.
Note 7:
Long term stability is V
REF
@25°C measured during 1000 hrs.
Note 8:
Thermal hysteresis is defined as the change in +25°C output voltage before and after cycling the device from (-40°C to 125°C).
Note 9:
Dropout voltage is defined as the minimum input to output differential at which the output voltage drops by 0.5% below the value measured with a 5V
input.
