Note 1:
Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when
operating the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction
temperature, T
, the junction-to-ambient thermal resistance,
θ
, and the ambient temperature, T
. The maximum allowable power
dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The
θ
JA
of the power SOT23-5 is 220
°
C/W
mounted on a PC board.
The device is not guaranteed to function outside its operating rating.
V
EN
must be
≤
V
IN
The maximum suggested value of the programming resistor, whose series resistance is measured from feedback to ground, is 124k
. Use of
larger resistor values can cause errors in the output voltage due to the feedback input bias current.
Devices are ESD sensitive, handling precautions required.
