ROHM provides a recommended PCB layout in the application note AN1191, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The output capacitor value depends on the output voltage, output current, and desired ripple voltage. ROHM recommends using a capacitor with a value between 10uF to 100uF, and a voltage rating of at least 2x the output voltage. A higher value capacitor can reduce ripple voltage but may increase startup time.
While the datasheet specifies an operating temperature range of -40°C to 85°C, ROHM recommends keeping the ambient temperature below 70°C for reliable long-term operation. Higher temperatures can reduce the device's lifespan and affect performance.
Yes, the LB-602MK2 is designed to withstand vibrations up to 10G (10Hz to 2kHz). However, it's essential to ensure proper PCB mounting and component soldering to prevent mechanical stress and damage.
ROHM provides a troubleshooting guide in the application note AN1191, which covers common issues such as output voltage deviation, oscillation, and overheating. It's essential to follow the guide and check the PCB layout, component values, and input/output connections before contacting ROHM support.
