Three low-ripple output voltages are available as standard: 3.3V, 5V or 12V with 500mA continuous output current rating over the full operating temperature range of -40C to +75C without derating. An enable connection allows power sequencing or very low standby consumption Power Module (3.5A) for battery powered applications. These modules can be SMD reflow soldered. The connection pads have corner half-vias to enable optical inspection of the joints after soldering. Selection Guide Part Input Output Output Efficiency Number Voltage Range Voltage Current typ.
