1. The S9V11F3S5C3 is a 3.3V step-up/step-down voltage regulator from Pololu. It provides a wide input voltage range (2.5 V to 11.8 V) and a fixed 3.3 V output with a 2A peak load capability.
2. This regulator features four selectable performance settings via two integrated Strapping Pins allowing users to set their required output voltage, switch frequency, current limit and power-saving feature. The S9V11F3S5C3 is a combination of a step-up converter and a linear (LDO) regulator to offer improved efficiency at both light and heavy loads, and extended output voltage range.
3. The S9V11F3S5C3 is a great choice for applications that require high efficiency, low cost, and advanced configurability. It is provided in a 3.3 mm × 3.3 mm QFN package, offering robust performance in a small form factor.
