Standard Connection Circuit Diagram
Figure 6
Note 1: When not using the ON/OFF control, keep ON/OFF pin open.
Note 2: When not adjusting output, keep V.ADJ pin open.
Note 3: When it includes inductance in input line or switch ing element is connected to the input side or the wire is long,
to fulfill the performance C1 will be required. Also to lower the input impedance we recommend a pattern that has an
additional C1, and to verify on a actual equipment. Or, by adding C2 you can lower the output ripple more.
Recommended Capacitor
C1=33 μF10WV
C2=2.2 μF~22μF
C2: An output capacitor is built-in so it is not required, however by connecting 2.2 μF~22 μF you can lower the noise more
Note 4: There is no +S, Pin in TSI 20N-0510V SIP type.
Method of Adjusting Output Voltage
When using at 3.3V without adjusting output voltage, keep V.ADJ pin (12Pin) open.
By connecting a resistor between +Vout pin (9~11Pin)~V.ADJ pin (12Pin), you can adjust the output voltage in the range of 0.8~3.3V.
(Vout Down Control)
By connecting a resistor between Vadj pin (12Pin)~GND pin (5~8Pin), you can adjust the output voltage in the range of 3.3V~3.6V.
(Vout Up Control)
To calculate external resistance, please refer to the equation below. After calculating external resistance, please check output voltage
and adjust resistance value.
