Semtron STD1807
The STD1807 is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering up to 1.5A of output current. The device operates from an input voltage range of 2.5V to 6.0V and provides an output voltage from 0.6V to VIN, making the STD1807 ideal for low voltage power conversions. This low noise output along with its excellent efficiency achieved by the internal synchronous rectifier, making STD1807 an ideal green replacement for large power consuming linear regulators.DESCRIPTION
1.5MHz, 1.5A, Synchronous Step Down DC/DC Converter●FEATURE Running at a fixed frequency of 1.5MHz allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermaloverload protection improves design reliability. STD1807S5-TRG ROHS Compliant This is Halogen Free
