With only 3 components count, SC189ZULTRT is the 1.5A Fixed 3.3V Step Down Switching Buck Regulator that requires only 25 mm x mm PCB Space. A simple 10uF and 22uF Input and Output Capacitor along with the 1uH 2A Inductor is all that is needed to use this regulator. This also have superior low shutdown current as well as 93% and above efficiency.
Features of SC189ZULTRT –
1. 1.5A of output current
2. 3.3V Fixed Voltage
3. Only 3 Components required and Only 25 square mm space is needed.
4. 2.9V – 5.5V Output
5. Less than 1uA Shutdown current making it excellent for battery power operations.
6. Output Over Voltage, Short-Circuit, Current Limit, Over Temperature Protection.
