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. This regulator is available with a fixed 3.3 V, 5 V, 9 V, or 12 V output.

Features:

Input voltage: [output voltage + dropout voltage] to 42 V (see below for more information on dropout voltage)
Fixed 3.3 V, 5 V, 9 V, or 12 V output (depending on regulator version) 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
Small size: 0.5″ × 0.4″ × 0.1″ (13 mm × 10 mm × 3 mm)
