The compact (0.4 0.5) D24V5F3 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 3.3 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 80% and 90% and has a very low dropout, so it can be used with input voltages as low as a few hundred millivolts above 3.3 V. The pins have a 0.1 spacing, making this board compatible with standard solderless breadboards and perfboards.
Features

• Input voltage:
• 3 V to 36 V for output voltages of 1.8 V and 2.5 V
• [output voltage + dropout voltage] to 36 V for output voltages of 3.3 V and higher (see below for more information on dropout voltage)
• Fixed 1.8 V, 2.5 V, 3.3 V, 5 V, 6 V, 9 V, 12 V, or 15 V output (depending on regulator version) with 4% accuracy
• Maximum output current: 500 mA
• Typical efficiency of 80% to 93%
• 500 kHz switching frequency (when not in power-save mode)
• 200 A typical no-load quiescent current
• Integrated over-temperature and over-current shutoff
• Small size: 0.5 0.4 0.1 (13 mm 10 mm 3 mm)
