5 / 26 page  LM3501 www.ti.com SNVS230B – MAY 2004 – REVISED MAY 2005 Electrical Characteristics Specifications in standard type face are for TA = 25°C and those in boldface type apply over the Operating Temperature Range of TA = −10°C to +85°C. Unless otherwise specified VIN = 2.7V and specifications apply to both LM3501-16 and LM3501-21.

All room temperature limits are production tested, guaranteed through statistical analysis or guaranteed by design. All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). (2) Typical numbers are at 25°C and represent the most likely norm. (3) Feedback current flows out of the pin. (4) Current flows into the pin.
