... Only two small external capacitors are needed for the charge pump. Output currents with greater than 99% efficiency are achievable. The ADM8828 also features a low power shutdown (SHDN) pin. This can be used to disable the device and reduce the quies- cent current to 20 nA. ...

... For maximum effi- ciency, capacitors with low ESR are, therefore, recommended. Shutdown Input The ADM8828 contains a shutdown input that can be used to disable the device and hence reduce the power consumption. A logic high level on the SHDN input shuts the device down reducing the quiescent current to 0 ...
