Note 1: Stresses beyond the “Absolute Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only. Functional operation of the device at these or any other conditions beyond
those indicated in the operational sections of the specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note 2: θJA is measured in the natural convection at TA = 25°C on a low effective single layer thermal
conductivity test board of JEDEC 51-3 thermal measurement standard. Pin 2 of SOT23-5 packages is the
case position for θJC JC measurement.

ACE does not assume any responsibility for use as critical components in life support devices or systems
without the express written approval of the president and general counsel of ACE Technology Co., LTD.
As sued herein:
1. Life support devices or systems are devices or systems which, (a) are intended for surgical implant
into the body, or (b) support or sustain life, and shoes failure to perform when properly used in
accordance with instructions for use provided in the labeling, can be reasonably expected to result in
a significant injury to the user.
2. A critical component is any component of a life support device or system whose failure to perform can
be reasonably expected to cause the failure of the life support device or system, or to affect its safety
or effectiveness.
