3.3V/1.0V and 1.8V for DDR2
1.2. U103, U104 (L5985 VFQFPN8)
Description
The L5985 is a step down switching regulator with 2.5A current limited embedded power MOSFET, so it is able to deliver up to 2A DC current to the load
depending on the application condition.
The input voltage can range from 2.9V to 18V, while the output voltage can be set starting from 0.6V to V
IN
. Having a minimum input voltage of 2.9V, the
device is suitable for buses staring from for 3.3V bus.
Requiring a minimum set of external components, the device includes an internal 250KHz switching frequency oscillator that can be externally adjusted up
to 1MHz.
The QFN package with exposed pad allows reducing the R
thJA
down to approximately 60°C/W.
