Analog DevicesADP5138WACPZ-1-R7DC/DC-Wandler und Spannungsregler-Chip
Quad, 1 A, 5.5 V, Synchronous Step-Down Regulators with One RF LDO Regulator
Product Description
The ADP5138 integrates four high performance synchronous step-down regulators and one low noise radio frequency (RF) low dropout (LDO) regulator. The device runs from PVINx input voltages of 3 V to 5.5 V. The output voltage of each channel is factory set or can be programmed down to 0.8 V with a resistor. Each step-down regulator can provide up to 1 A of continuous output current and the LDO can provide 250 mA of output current.
