RESET Output Delay Hold Time td
The NJW4116 has the RESET Output Delay Hold Time td till the RESET outputs “H” in order to prevent malfunction
due to chattering after the Output Voltage VO exceeds the RESET release voltage VDETH (=VDET+VHYS).
The td is decided by capacitance connected to Cd pin as follows:
External delay capacitor [nF] = (Required) RESET Delay Hold Time td [ms] / 10[ms] x 4.7[nF]

*Input Capacitor CIN
The input capacitor CIN is required in order to prevent oscillation and reduce power supply ripple of applications when
high power supply impedance or a long power supply line.
Therefore, the recommended capacitance (refer to conditions of ELECTRIC CHARACTERISTIC) or larger input
capacitor, connected between VIN and GND as short path as possible, is recommended in order to avoid the problem.
*Output Capacitor CO
The output capacitor CO is required for a phase compensation of the internal error amplifier, and the
capacitance and the equivalent series resistance (ESR) influence stable operation of the regulator.
If use a smaller output capacitor than the recommended capacitance (refer to conditions of ELECTRIC
CHARACTERISTIC), it may cause excess output noise or oscillation of the regulator due to lack of the phase
compensation. Therefore, the recommended capacitance or larger output capacitor, connected between VOUT and
GND as short path as possible, is recommended for stable operation. The recommended capacitance may be
different by output voltage, therefore confirm the recommended capacitance of the required output voltage.
Furthermore, a larger output capacitor reduces output noise and ripple output, and also improves Output
Transient Response when a load changes rapidly.
Selecting the output capacitor, should consider varied characteristics of a capacitor: frequency characteristics,
temperature characteristics, DC bias characteristics and so on. Therefore, the capacitor that has a sufficient margin of
the rated voltage against the output voltage and superior temperature characteristics, is recommended for CO.
