Other Parts Discussed in Thread: TL1963A
Hi,
i'm testing out TL1961AEVM whereby I've switched out the KKT package device into a SOT-223 device. I'm setting the input voltage to 12V and output 10V, output loaded with 800mA. I found that the measured temperature at the top of regulator is 94.5'C at room temp, this result will failed the spec at ambient temp 70'C. Since the dropout is just 2V and output load is around 50% of maximum (1.5A), are there any factors i need to look into to ID root cause the high heat dissipation?
Regards,
Leo
