The Pololu 3.3V, 100mA Step-Down Voltage Regulator D45V1E2F3 is a compact synchronous buck regulator designed to convert high input voltages up to 65 V into a stable 3 V output. It delivers up to 100 mA of continuous current with high efficiency, especially at low currents, due to its low quiescent current. This regulator features a precision-threshold enable input for on/off control and a power-good output for voltage monitoring and sequencing. It includes short-circuit and thermal shutdown protection to prevent damage from overheating.
