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) Dropout voltage is the voltage difference between the input and the output at which the output voltage drops to 100 mV below its nominal value. (6) Specification ensured by design. Not tested during production. 10 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Product Folder Links: LM10507 |
