All electrical characteristics having room-temperature limits are tested during production with TJ = 25°C. All hot and cold limits are ensured by correlating the electrical characteristics to process and temperature variations and applying statistical process control. (2) Capacitors: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) are used in setting electrical characteristics. (3) Unless otherwise noted, VIN = 5.0V where: VIN = VVIN_B1 = VVIN_B2 = VVIN_B3. Limits apply for TJ = 25°C unless otherwise noted. (4) Limits apply over the entire operating junction temperature range of −30°C ≤TA = TJ ≤ +85°C. (5) Specification ensured by design. Not tested during production. 6 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Product Folder Links: LM10507 |
