Datasheet

If you need more output current, consider our D15V35F5S3 and D15V70F5S3 3.3V/5V step-down
voltage regulators, which can typically deliver a continuous 3.5 A and 7 A, respectively.
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)
• 550 kHz 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)
Using the Regulator
Connections
The buck regulator has four connections: shutdown (SHDN), input voltage (VIN), ground (GND), and
output voltage (VOUT).
