Electrical Characteristics (continued)

Unless otherwise specified: VIN = 2.5 V, IOUT = 10 mA, CIN = 10 µF, COUT = 10 µF, VEN = 2 V, and limits apply for 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.
