LT3014 micropower device output transient response will function output capacitance. Larger values output capacitance decrease peak deviations provide improved transient response larger load current changes. Bypass capacitors, used decouple individual components powered LT3014, will increase effective output capacitor value. Extra consideration must given ceramic capacitors. Ceramic capacitors manufactured with variety dielectrics, each with different behavior across temperature applied voltage. most common dielectrics used specified with temperature characteristic codes Z5U, Y5V, X7R. dielectrics good providing high capacitances small package, they tend have strong voltage temperature coefficients shown Figures When used with regulator, capacitor exhibit effective value bias voltage applied over operating temperature range. dielectrics result more stable characteristics more suitable output capacitor. type better stability across temperature, while less expensive available higher values. Care still must exercised when using capacitors; codes only specify operating temperature range maximum capacitance change over temperature. Capacitance change bias with capacitors better than capacitors, still significant enough drop capacitor values below appropriate levels. Capacitor bias characteristics tend improve component case size increases, expected capacitance operating voltage should verified.

Current flow back into output will follow curve shown Figure rise reverse output current above occurs from breakdown clamp pin. With resistor divider regulator output, this current will reduced depending size resistor divider. When LT3014 forced below pulled above pin, input current will typically drop less than This happen input LT3014 connected discharged (low voltage) battery output held either backup battery second regulator circuit. state SHDN will have effect reverse output current when output pulled above input.
