6 / 38 page LM21215A SNOSB87C – MARCH 2011 – REVISED JANUARY 2016 www.ti.com Electrical Characteristics (continued) Unless otherwise stated, the following conditions apply: VPVIN = VAVIN= 5 V, TJ = 25°C. Minimum and maximum limits are specified through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C and are provided for reference purposes only.
