1 Use a minimum 2 x 220uF output capacitor. Recommended capacitor is Nichicon PM series, 220uF/35V. If the ambient temperature at module
startup is between 0 O C and -10 O C, use a minimum 3 x 220uF capacitors, and between -10 O C and -20 O C, use a minimum 4 x 220uF capacitors. For
startup below -20 O C, use 440uF minimum polymer capacitors.
2 External capacitors may require using the new Tunable Loop feature to ensure that the m odule is stable as well as getting the best transient
response. See the Tunable Loop section for details.
