Data Sheet ADP2370/ADP2371 RECOMMENDED SPECIFICATIONS: CAPACITORS Table 2. Parameter Symbol Test Conditions/Comments Min Typ Max Unit
MINIMUM INPUT and OUTPUT CAPACITANCE1 CMIN TA = −40°C to +125°C 6.5 10 µF CAPACITOR ESR RESR TA = −40°C to +125°C 1 10 mΩ 1 The minimum input and output capacitance should be greater than 7 μF over the full range of operating conditions. The full range of operating conditions in the application must be considered during device selection to ensure that the minimum capacitance specification is met. X7R- and X5R-type capacitors are recommended; Y5V and Z5U capacitors are not recommended for use with any buck. Rev.
