PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
PIN FUNCTION TABLE
3.1
Ground Terminal (GND)
Regulator ground. Tie GND to the negative side of both
the output and the input capacitor. Only the LDO bias
current (2 μA, typical) flows out of this pin, as there is
no high current. The LDO output regulation is refer-
enced to this pin. Minimize voltage drops between this
pin and the negative side of the load.
3.2
Regulated Voltage Output (V
OUT
)
Connect V
OUT
to the positive side of the load and the
positive terminal of the output capacitor. The positive
side of the output capacitor should be located as close
as possible to the LDO V
OUT
pin. The current flowing
out of this pin is equal to the DC load current.
3.3
Unregulated Supply Input (V
IN
)
Connect the input supply voltage and the positive side
of the input capacitor to V
IN
. Like all low dropout linear
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 located as close as
possible to the V
IN
pin. For most applications, 1 μF of
capacitance will ensure stable operation of the LDO
circuit. For applications 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 ESR charac-
teristics of the ceramic will yield better noise and PSRR
performance at high frequencies. The current flow into
this pin is equal to the DC load current, plus the LDO
bias current (2 μA, typical).
