Electrical Characteristics (continued)
Unless otherwise specified V_IN = 3.3 V, I_OUT = 10 mA, C_IN = 10 μF, C_OUT = 10 μF, V_EN = V_IN, V_OUT = 1.8 V. Minimum and
maximum limits apply over the junction temperature (T_J) range of –40°C to +125°C and are specified through test, design, or
statistical correlation. Typical values represent the most likely parametric norm at T_J = 25°C, and are provided for reference
purposes only.
