DESCRIPTION
A logic input control to enable the regulator output. When EN is asserted (logic high), it allows out-
put regulation to commence. When EN is deasserted (logic low), the regulator pass transistor (N-
channel MOSFET) is forced into a high impedance mode.
All other internal circuitry is unaffected by the state of the EN input and will always remain powered
whenever V
An internal pull-up current (2µA) from V
EN control input.
The EN control input is intended to be used for power-up sequencing.
The input power supply for the regulator. If this input is within a few inches of the main supply filter,
a capacitor may not be necessary. Otherwise an input filter capacitor of approximately 1uF to 10uF
will ensure adequate filtering.
The regulator voltage output used to power the load. A nominal output capacitor of 10uF is suffi-
cient to minimize any transient disturbances under normal operating conditions. Additional output
capacitance can be used to further improve transient load response.
These pins have no connection to the internal device. To provide additional thermal performance,
these pins can be connected directly to the PC board GND plane.
The negative reference for all voltages.
