Application Hints EXTERNAL CAPACITORS Like any low-dropout regulator, the LP2985LV requires ex- ternal capacitors for regulator stability. These capacitors must be correctly selected for good performance. Input Capacitor An input capacitor whose capacitance is ≥ 1 µF is required between ...
Page 12
Application Hints (Continued) One disadvantage of ceramic capacitors is that their capaci- tance can vary with temperature. Most large value ceramic capacitors (≥ 2.2 µF) are manufactured with the Z5U or Y5V temperature characteristic, which results in the capacitance dropping ...
