STMicroelectronics L7986TR, 1 Linear Voltage, Voltage Regulator 3A, 0.6 → 38 V 10-Pin, VFDFPN

The L7986/A is a step-down switching regulator with a 3.7 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 3 A current to the load depending on the application conditions. The input voltage can range from 4.5 V to 38 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 DFN and the HSOP packages with exposed pad allow reducing the RthJAdown to 60 °C/W and 40 °C/W respectively.3 A DC output current 4.5 V to 38 V input voltage Output voltage adjustable from 0.6 V 250 kHz switching frequency, programmable up to 1 MHz Internal soft-start and enable Low dropout operation: 100% duty cycle Voltage feed-forward Zero load current operation Overcurrent and thermal protection Applications Consumer: STB, DVD, DVD recorder, car audio, LCD TV and monitors Industrial: PLD, PLA, FPGA, chargers Networking: XDSL, modems, DC-DC modules Computer: optical storage, hard disk drive, printers, audio/graphic cards LED driving
