NOTE:
1. Limits are 100% production tested at 25

C. Limits over the operating temperature range are guaranteed through correlation using Statistical
Quality Control (SQC) methods.
2. Ceramic capacitors. Low ESR Electrolytic capacitors are not required for stability, but may be needed for the application.
