Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
(Maximum junction temperature),
θ
JA
(junction to am-
bient thermal resistance), and T
A
(ambient temperature). The maximum allowable power dissipation at any temperature is P
DMAX
= (T
JMAX
− T
A
)/θ
JA
or the number
given in the Absolute Maximum Ratings, which ever is lower.
θ
JA
= 150˚C/W.
Note 3:
The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. Enable pin ESD threshold is 1.7kV.
Note 4:
Thermal Shutdown will protect the device from permanent damage.
Note 5:
For LM3526-L, OFF is EN
≥
2.4V and ON is EN
≤
0.8V. For LM3526-H, OFF is EN
≤
0.8V and ON is EN
≥
2.4V.
