Calculation Example
Example 1) When Ta=85, Vcc=8.3V, Vo=3.3V, BA33DD0WT
Io
1.048.3×Icca

Io 200mA (Icca : 2mA)
With the IC alone : θja=62.5/W -16mW/
25=2000mW 85=1040mW
Please refer to the above information and keep thermal designs within the scope of acceptable loss for all operating
temperature ranges. The power consumption Pc of the IC when there is a short circuit (short between Vo and GND) is:
Pc=Vcc×(IccaIshort)
Ishort : Short circuit current
Terminal Vicinity Settings and Cautions
Vcc Terminal
Please attach a capacitor (greater than 0.33μF) between the Vcc and GND.
The capacitance values differ depending on the application, so please chose a capacitor with sufficient margin and verify
the operation on an actual board.
CTL Terminal
The CTL terminal is turned ON at 2.0V and higher and OFF at 0.8V and lower within the operating power supply voltage
range.
CC0xx series, The power supply and the CTL terminal in any order without problems.
Vo Terminal
Please attach an anti-oscillation capacitor between VOUT and GND. The capacitance of the capacitor may significantly
change due to factors such as temperature changes, which may cause oscillations. Please use a tantalum capacitor or
aluminum electrolytic capacitor with favorable characteristics and small external series resistance (ESR) even at low
temperatures. The output oscillates regardless of whether the ESR is large or small. Please use the IC within the stable
operating region while referring to the ESR characteristics reference data shown in Fig.31 through 33. In cases where there
are sudden load fluctuations, the large capacitor is recommended.
