Electrical Characteristics (continued)
Limits in standard type are for TJ = 25°C unless otherwise specified. Minimum and Maximum limits are ensured 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. Unless otherwise stated the following conditions apply: VIN = 12 V, VOUT = 1.8 V
