Description
General part information
L7980 Series
The L7980 device is a step-down switching regulator with a 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 RthJAdown to 60 °C/W and 40 °C/W respectively.2 A DC output current4.5 V to 28 V input voltageOutput voltage adjustable from 0.6 V250 kHz switching frequency, programmable up to 1 MHzInternal soft-start and enableLow dropout operation: 100% duty cycleVoltage feed-forwardZero load current operationOvercurrent and thermal protectionVFQFPN 3 x 3 - 8L and HSOP8 package
