REJ03B0274-0110 Rev.1.10 Sep 28, 2009
Under development Preliminary specification
Specifications in this manual are tentative and subject to change.
Notes:
1. VCC = 1.8 to 5.5 V and Topr =
20 to 85°C (N version), unless otherwise specified.
2. The average output current indicates the average value of current measured during 100 ms.
