*Input Capacitance C
IN
Input Capacitance (C
IN)
) is 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
IN
value of 0.1µF greater to avoid the problem.
C
IN
should connect between GND and V
IN
as short as possible.
*Output Capacitance C
O
Output capacitor (C
O
) is required for a phase compensation of the internal error amplifier. The capacitance and the
equivalent series resistance (ESR) influences stability of the regulator.
This product is designed to work with a low ESR capacitor for the C
O
; however, use of recommended capacitance or
greater value is essential for stable operation.
Use of a smaller C
O
may cause excess output noise or oscillation of the regulator due to lack of the phase
compensation.
Therefore, use C
O
with the recommended capacitance or greater value and connect between V
O
terminal and
GND terminal with minimal wiring. The recommended capacitance depends on the output voltage. Low voltage
regulator requires greater value of the C
O
. Thus, check the recommended capacitance for each output voltage.
Use of a greater C
O
reduces output noise and ripple output, and also improves transient response of the output
voltage against rapid load change.
