The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
3.1
Regulator ground. Tie GND to the negative side of the
output and the negative side of the input capacitor.
Only the LDO bias current (2 µA, typ.) flows out of this
pin, there is no high current. The LDO output regulation
is referenced to this pin. Minimize voltage drops
between this pin and the negative side of the load.
3.2
Connect V
positive terminal of the output capacitor. The positive
side of the output capacitor should be physically
located as close as possible to the LDO V
current flowing out of this pin is equal to the DC load
current.

Connect the input supply voltage and the positive side
of the input capacitor to V
regulators, low source impedance is necessary for the
stable operation of the LDO. The amount of
capacitance required to ensure low source impedance
will depend on the proximity of the input source
capacitors or battery type. The input capacitor should
be physically located as close as possible to the V
pin. For most applications, 1 µF of capacitance will
ensure stable operation of the LDO circuit. For applica-
tions that have load currents below 100 mA, the input
capacitance requirement can be lowered. The type of
capacitor used can be ceramic, tantalum or aluminum
electrolytic. The low equivalent series resistence
characteristics of the ceramic will yield better noise and
PSRR performance at high frequency. The current flow
into this pin is equal to the DC load current, plus the
LDO bias current (2 µA, typ.).
