תיאור

Pololu 3.3V, 300mA Step-Down Voltage Regulator D24V3F3

The compact (0.4″×0.5″) D24V3F3 switching step-down (or buck) voltage regulator takes an input voltage between 4.3V and 42V and efficiently reduces it to3.3Vwhile allowing for a maximum output current of300mA. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

Features

Input voltage: [outputvoltage+dropoutvoltage] to 42V (see below for more information on dropout voltage)
Fixed 3.3V, 5V, 9V, or 12V output (depending on regulator version) with 4% accuracy
Maximum output current: 300mA or 600mA (depending on regulator version)
1.25MHz switching frequency
2mA typical no-load quiescent current (20μA typical quiescent current withSHDN= LOW)
Integrated over-temperature and over-current shutoff
Small size: 0.5″×0.4″×0.1″ (13mm×10mm×3mm)
