sSelecting External components for dropper type regulator
Input capacitor (Approx. 47
F)
Output capacitor (Approx. 47 to 100
F)
qLow ESR capacitors are recommended for input and output when using them in low temperature conditions (0
°C or less)
sSelecting External components for switching type regulator
Input capacitor (Approx. 100
F)
Output smoothing capacitor (Approx. 330
F)
qInput capacitor and output capacitor must satisfy allowable ripple current.
qLow ESR capacitors are recommended for reducing output ripple voltage.
qLow ESR capacitors are recommended for input and output when using them in low temperature conditions (0
°C or less)
Choke coil (200
H when VO is 3.3V or 5V, 300H when VO is not 3.3V or 5V)
qWhen its winding resistance is high, its efficiency may decrease and the rated value may not be achieved.
qPay attention to heat from the choke coil due to magnetic saturation caused by overload, short circuit of load, etc. because the overcurrent
protection starting current is approx. 1A.
Flywheel diode (Sanken AK04 recommended)
qUse a Schottky barrier diode for D1, D2 and D3 and make sure that the reverse voltage applied to SW output terminal does not exceed the value
(–1V) given in the maximum ratings.
qIf you use a fast recovery diode or any other diode, application of a reverse voltage generated from the recovery or ON voltage of the diode may
damage the IC.
