    voltages set for greater than 24V, use a minimum output
    capacitor of 4.7μF. The LT3060 is a micropower device
    and output load transient response is a function of output
    capacitance. Larger values of output capacitance decrease
    the peak deviations and provide improved transient
    responseforlargerloadcurrentchanges.Bypasscapacitors,
    used to decouple individual components powered by the
    LT3060, increase the effective output capacitor value. For
    applications with large load current transients, a low ESR
    ceramic capacitor in parallel with a bulk tantalum capacitor
    often provides an optimally damped response.
    Give extra consideration to the use of ceramic capacitors.
    Manufacturers make ceramic capacitors with a variety of
    dielectrics, each with different behavior across tempera-
    ture and applied voltage. The most common dielectrics
    are specied with EIA temperature characteristic codes
    of Z5U, Y5V, X5R and X7R. The Z5U and Y5V dielectrics
    provide high C-V products in a small package at low cost,
    but exhibit strong voltage and temperature coefcients, as
    shown in Figures 4 and 5. When used with a 5V regulator,
    a 16V 10μF Y5V capacitor can exhibit an effective value
    as low as 1μF to 2μF for the DC bias voltage applied, and
    over the operating temperature range. The X5R and X7R
    dielectrics yield much more stable characteristics and are
    more suitable for use as the output capacitor.
    The X7R type works over a wider temperature range and
    has better temperature stability, while the X5R is less
    expensive and is available in higher values. Care still must
    be exercised when using X5R and X7R capacitors; the X5R
    and X7R codes only specify operating temperature range
    and maximum capacitance change over temperature.
    Capacitance change due to DC bias with X5R and X7R
    capacitors is better than Y5V and Z5U capacitors, but can
    still be signicant enough to drop capacitor values below
    appropriate levels. Capacitor DC bias characteristics tend
    to improve as component case size increases, but expected
    capacitance at operating voltage should be veried.
    Voltageandtemperaturecoefcientsarenottheonlysources
    of problems. Some ceramic capacitors have a piezoelectric
    response. A piezoelectric device generates voltage across
    its terminals due to mechanical stress, similar to the way
    a piezoelectric accelerometer or microphone works. For a
    ceramic capacitor, the stress is induced by vibrations in
    the system or thermal transients. The resulting voltages
    produced cause appreciable amounts of noise. A ceramic
    capacitor produced the trace in Figure 6 in response to light
    tapping from a pencil. Similar vibration induced behavior
    can masquerade as increased output voltage noise.
