ADP5014ACPZ-R7

The ADP5014 combines four high performance, low noise buck regulators in a 40-lead LFCSP package. Relying on its low output noise (~25 μV rms when VoUT ≤ VREF), the low noise buck regulator enables the powering up of the noise sensitive signal chain products. All channels in the ADP5014 integrate high-side and low-side power metal-oxide semiconductor field effect transistors (MOSFET). Channel 1 and Channel 2 deliver a programmable output current of 2 A or 4 A. Combining Channel 1 and Channel 2 in a parallel configuration provides a single output with up to 8 A of current. Channel 3 and Channel 4 deliver a programmable output current of 1 A or 2 A. Combining Channel 3 and Channel 4 in a parallel configuration can provide a single output with up to 4 A of current.
