Description
Unregulated supply input.
Ground terminal.
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, output voltage falls to zero and supply current is reduced to 0.05 microamp
(typical).
Out-of-Regulation Flag. (Open drain output). This output goes low when V
OUT
is out-of-
tolerance by approximately – 5%.
Reference bypass input. Connecting a 470pF to this input further reduces output noise.
Regulated voltage output.

3. Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load
range from 0.1mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the
thermal regulation specification.
4. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value.
5. Ground pin current is the regulator pass transistor gate current. The total current drawn from the input supply is the sum of the load
current, ground current and supply current (i.e. I
IN
= I
SUPPLY
+ I
GND
+ I
LOAD
).
6. Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load
or line regulation effects. Specifications are for a current pulse equal to I
LMAX
at V
IN
= 6V for T = 10msec.
7. The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the
thermal resistance from junction-to-air (i.e. T
A
, T
J
, q
JA
). Exceeding the maximum allowable power dissipation causes the device to
initiate thermal shutdown. Please see Thermal Considerationssection of this data sheet for more details.
