D24V5Fx Step-Down Voltage Regulators
The D24V5x family of 500 mA synchronous buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 36 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters), which makes them much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. These regulators have very low drop-out voltages.
The regulators feature short-circuit/over-current protection, and thermal shutdown helps prevent damage from overheating. The boards do not have reverse-voltage protection.
This family consists of eight fixed-output versions ranging from 1.8 V to 15 V:
