Pololu 12V 600mA Step-Down Voltage Regulator (14-42V Input D24V6F12)

The regulator has short-circuit protection, and thermal shutdown prevents damage from overheating. The board does not have reverse-voltage protection.

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)
