The thermal resistances (R) are based on JEDEC board, and the characterization parameters (Ψ) are based on the EVM described in

the Layout section. For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal

Metrics application report.

6.5 Electrical Characteristics

Over operating temperature range (TJ = –40°C to 150°C), VVINP = 5.0V, CIN1 = COUT1 = 15nF, CIN2 = 10µF, COUT2 = 22µF

SEL connected to VCC, VEN/FLT = 5.0V unless otherwise noted. All typical values at VVINP=5.0V, TA = 25°C.
