LM341-12, LM78M12C ELECTRICAL CHARACTERISTICS

Unless otherwise specified: VIN = 19V, CIN = 0.33 μF, CO = 0.1 μF

Limits in standard typeface are for TJ = 25°C, and limits in boldface type apply over the −40°C to +125°C operating

temperature range. Limits are specified by production testing or correlation techniques using standard Statistical Quality

Control (SQC) methods.
