Electrical Specifications Unless otherwise noted, all parameters are guaranteed over the following specified conditions:

VIN =VOUT + 0.4V, VOUT = 1.8V, CIN = COUT = 220µF 25mΩ and 0.1µF X7R, TJ = +25°C, IL = 0A. Applications must follow thermal guidelines of

the package to determine worst-case junction temperature. Please refer to “Applications Information” on page 11 of the datasheet and

Tech Brief TB379. Boldface limits apply over the operating temperature range, -55°C to +125°C. Pulse load techniques used by ATE to ensure

TJ = TA defines guaranteed limits. (Continued)
