These pins provide a means of connecting the
compensation network for the on-chip regulator.
Ground.
Must be connected to system ground. Minimize the
ground path impedance for optimal performance of
the device.
External Biasing Resistor.
Used by on-chip circuitry to establish bias currents
within the device. This pin must be connected to
GND through a 10 k Ω (1%) resistor.
Reserved—No Connect.
This pin must be left unconnected for normal
operation.
Reserved—GND.
This pin must be tied to GND for normal operation.
