Key Features:
- Fixed 5 V output with 4% accuracy
- Maximum output current: 300 mA or 600 mA (depending on regulator version)
- 1.25 MHz switching frequency
- 2 mA typical no-load quiescent current (20 μA typical quiescent current with SHDN = LOW)
- Integrated over-temperature and over-current shutoff
These buck (step-down) voltage regulators generate lower output voltages from input voltages as high as 42 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 90%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large.
