ELECTRICAL CHARACTERISTICS (continued)

Unless otherwise specified: VIN = 2.5V, IOUT = 10 mA, CIN = 10 µF, COUT = 10 µF, VEN = VIN. Limits in standard type are for TJ

= 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -40°C to +125°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.

Device operation must be evaluated, and derated as needed, based on ambient temperature (TA), power dissipation (PD), maximum

allowable operating junction temperature (TJ(MAX)), and package thermal resistance (θJA).
