PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
PIN FUNCTION TABLE
3.1
Regulated Output Voltage (V
OUT
)
Regulated voltage output.
3.2
Ground (GND)
Ground terminal.
3.3
Reference Bypass (BYPASS)
Reference bypass input. Connecting a 470 pF to this
input further reduces output noise.
3.4
Out-of-Regulation Flag (ERROR)
Out-of-regulation flag (open-drain output). This output
goes low when V
OUT
is out-of-tolerance by
approximately -5%.
3.5
Shutdown Control (SHDN)
Shutdown control input. The regulator is fully enabled
when a logic-high is applied to this input. The regulator
enters shutdown when a logic-low is applied to this
input. During shutdown, the output voltage falls to zero
and the supply current is reduced to 0.05 μA (typical).
3.6
Unregulated Supply (V
IN
)
Unregulated supply input.
Pin No.
(8-Pin SOIC)
Pin No.
(5-Pin DDPAK)
