3.3V Step-Up/Step-Down Voltage Regulator w/ Fixed 3V Low-Voltage Cutoff S9V11F3S5C3

The Pololu S9V11F3S5C3 is a compact 3.3V step-up/step-down voltage regulator with a fixed 3V low-voltage cutoff. It can raise or lower the input voltage to keep a stable output, making it useful for battery-powered projects where the voltage can change during use. The output is set to 3.3V by default and can be changed to 5V using the SEL pin. Its fixed 3V cutoff helps protect batteries from over-discharging, while built-in short-circuit and over-temperature protection add extra safety during operation. Features: Output voltage: 3.3V default, 5V selectable Input voltage range: 3V to 16V Typical maximum output current: 1.5A Fixed 3V low-voltage cutoff Power-good indicator pin Low quiescent current under 1mA when enabled Short-circuit protection Over-temperature protection Size: 0.5″ × 0.6″ × 0.17″ Weight: 0.7g without headers
