The A7986A is a step-down switching regulator with a 3.7 A (min.) 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 HSOP8 package with exposed pad allows the reduction of Rth(JA) down to 40 °C/W.
