Electrical Characteristics (continued)

Unless otherwise specified VIN = 3.3 V, IOUT = 10 mA, CIN = 10 μF, COUT = 10 μF, VEN = VIN, VOUT = 1.8 V. Minimum and

maximum limits apply over the junction temperature (TJ) 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 TJ = 25°C, and are provided for reference

purposes only.
