ADP3335 Summary of contents
Page 1
... The ADP3335 achieves exceptional accuracy of ±0.9% at room temperature and ±1.8% over temperature, line, and load. The dropout voltage of the ADP3335 is only 200 mV (typical) at 500 mA. This device also includes a safety current limit, thermal overload protection, and a shutdown feature. In shutdown mode, the ground current is reduced to less than 1 μ ...

... These ESR limitations make designing with LDOs more difficult because of their unclear specifications and extreme variations over temperature. With the ADP3335, ESR limitations are no longer a source of design constraints. The ADP3335 can be used with virtually any good quality capacitor and with no constraint on the minimum ESR. This innovative design allows the circuit to be stable with just a small 1 μ ...

... APPLICATIONS INFORMATION OUTPUT CAPACITOR SELECTION As with any micropower device, output transient response is a function of the output capacitance. The ADP3335 is stable over a wide range of capacitor values, types, and ESR (anyCAP). A capacitor as low as 1 μF is all that is needed for stability; larger capacitors can be used if high output current surges are anticipated. The ADP3335 is stable with extremely low ESR capacitors (ESR ≈ ...

... ADP3335. For optimum heat transfer, specify thick copper and use wide traces not recommended to use solder mask or silkscreen on the PCB traces adjacent to the ADP3335’s pins, since doing so will increase the junction-to-ambient thermal resistance of the package. 5. ...
