STMicroelectronics L5986
The L5986 is a step-down switching regulator with a 3.0 A (min.) current limited embedded Power MOSFET, so it is able to deliver up to 2.5 A current to the load depending on the application conditions. The input voltage can range from 2.9 V to 18 V, while the output voltage can be set starting from 0.6 V to VIN. The QFN and the HSOP packages with an exposed pad allow reducing the RthJA down to 60 °C/W and 40 °C/W respectively.FEATURES
● 2.5 A DC output current● 2.9 V to 18 V input voltage
● Output voltage adjustable from 0.6 V
● 250 kHz switching frequency, programmable up to 1 MHz
● Internal soft-start and inhibit
● Low dropout operation: 100% duty cycle
DESCRIPTION
Having a minimum input voltage of 2.9 V, the device is suitable also for a 3.3 V bus.● Voltage feedforward
● Zero load current operation
● Overcurrent and thermal protection
● VFQFPN 3 x 3 mm -8L and HSOP8 package
APPLICATIONS
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.● Consumer: STB, DVD, DVD recorder, car audio, LCD TV and monitors Figure 1.
