7.5 General Electrical Characteristics⁽¹⁾⁽²⁾
Unless otherwise noted, V_IN = 5 V where: V_IN = V_{VIN_B1} = V_{VIN_B2} = V_{VIN_B3}. Limits apply for T_J = 25°C, unless otherwise noted.

(1) All limits are ensured by design, test and/or statistical analysis. All electrical characteristics having room-temperature limits are tested
during production with T_J = 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) Limits apply over the entire operating junction temperature range of −40°C ≤ T_A = T_J ≤ 85°C.
(4) Specification ensured by design. Not tested during production.
