Electrical Characteristics
LP38501/3–ADJ
Unless otherwise specified: V_IN = 3.3V, I_OUT = 10 mA, C_IN = 10 µF, C_OUT = 10 µF, V_EN = V_IN, V_OUT = 1.8V. Limits in standard type
are for T_J = 25°C only; limits in boldface type apply over the junction temperature (T_J) range of -40°C to +125°C. Minimum and
Maximum limits are guaranteed 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.
