The connecting wiring of C O and each terminal must be as short as possible. Owing to type, value and wiring condition of capacitor, it may oscillate. Confirm the output waveform under the actual condition before using. 2. ON/OFF control terminal 5 is compatible with LS-TTL. It enables to be directly drive by TTL or C-MOS standard logic (RCA4000 series) . If ON/OFF control terminal is not used, it is recommended to directly connect applicable terminals with input terminal. 3. If voltage is applied under the conditions that the device pin is connected divergently or reversely, the deterioration of characteristics or damage may occur. Never allow improper mounting. 4. If voltage exceeding the voltage of DC input terminal 1 is applied to the output terminal 2 , the element may be damaged. Especially when the DC input terminal 1 is short-circuited to the GND in ordinary operating state, charges accumulated in the output capacitor CO flow to the input side, causing damage to the element. In this case, connect the ordinary silicon diode as shown in the figure. 1 2 s Adjustment of Output Voltage 1. Output voltage is able to set (1.5V to 5V) when resistors R1, R2 are attached to 2 , 3 , 4 terminals. As for the external resistors to set output voltage, refer to the following figure and Fig.18. 2 R2 - + 3 Vref 4 R1 VO VO=Vrefx (1+R2/R1) =1.24x (1+R2/2000) =.
