State of control terminal:

•“H”→ output is enabled.

•“L” or “open” → output is disabled.

ꢂIn the case of using a resistance "R" between V_INand control.

The current flow into the control terminal while the IC is ON state (I_CONT) can be reduced when a pull up resistance

"R" is inserted between V_INand the control terminal.

The minimum control voltage for ON state (V_{CONT (ON)}) is increased due to the voltage drop caused by I_CONTand the

resistance "R". The I_CONTis temperature dependence as shown in the "Control Current vs. Temperature"

characteristics. Therefore, the resistance "R" should be carefully selected to ensure the control voltage exceeds

the V_{CONT (ON)}over the required temperature range.

ꢂInput Capacitance C_IN

Input Capacitance C_INis required to prevent oscillation and reduce power supply ripple for applications with high

power supply impedance or a long power supply line.

Use the C_INvalue of 4.7µF greater to avoid the problem.

C_INshould connect between GND and V_INas short as possible.

ꢂOutput Capacitance C_O

Output capacitor (Co) is required for a phase compensation of the internal error amplifier. The capacitance and the

equivalent series resistance (ESR) influence stability of the regulator.

If use a smaller Co, it may cause excess output noise or oscillation of the regulator due to lack of the phase

compensation. Therefore, use Co with the recommended capacitance or greater value and connect between Vo

terminal and GND terminal with minimal wiring.

The recommended capacitance depends on the output voltage. Low voltage regulator requires greater value of

the Co. Thus, check the recommended capacitance for each output voltage.

Use of a greater Co reduces output noise and ripple output, and also improves transient response of the output

voltage against rapid load change.

This product is designed to work with any capacitor including a low ESR capacitor for the Co; however, refer

"Equivalent Series Resistance vs. Output Current" and choose suitable capacitor.

ꢂ When distance from an IC to load is long, an IC may cause malfunction by wiring capacity and an L ingredient

Please use it after having evaluated it enough.
