DESCRIPTION
Positive input voltage for the regulator. The internal loading on this input is typically 300µA when-
ever the regulator is enabled, and less than 1µA when the regulator is disabled. Although an input
filter capacitor is not required, it is recommended that a 1µF ceramic capacitor be used for addi-
tional filtering and stability if this pin is greater than 2 inches from the main input filter.
The negative reference for all voltages.
Enable/shutdown input. When EN is asserted high (V

Power Good output. This is an open drain output and functions as a supply voltage supervisor for
the output voltage. It is asserted low when the output falls below 89% of its nominal value. This out-
put becomes inactive when V
The regulated voltage output. An output capacitor of 1µF is recommended to minimize any tran-
sient load disturbances under normal operating conditions. Additional output capacitance can be
used to further improve transient load response.
