Description

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

QFN and the HSOP packages with exposed pad

allow reducing the RthJA down to 60 °C/W and 40

°C/W respectively.
