Preliminary DataThis is preliminary information on
DescriptionThe L7980/A is a step down switching regulator with 2.5 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 2 A current to the load depending on the application conditions.The input voltage can range from 4.5 V to 28 V, while the output voltage can be set starting from 0.6 V to VIN .Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.The QFN and the HSOP packages with exposed pad allow reducing the RthJA down to 60 C/W and 40 C/W respectively.QFN 3x3HSOP-8Exposed padwww.st.comFigure 1.Application circuitContentsL79802/19 Contents1Pin settings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 31.1Pin connection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 31.2Pin description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
