Notes:
a. Room = 25 °C, Full = - 40 °C to 85 °C.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. Typical values for dropout voltage at V
OUT
≥
2 V
are measured at VOUT = 3.3 V, while typical values for dropout voltage at V
OUT
< 2 V are measured at V
OUT
= 1.8 V.
d. Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2 % below the output voltage measured
with a 1 V differential, provided that V
IN
does not drop below 2.0 V.
e. Ground current is specified for normal operation as well as “drop-out” operation.
f. The device’s shutdown pin includes a typical 2 MΩ internal pull-down resistor connected to ground.
g. V
OUT(nom)
is V

Function
By applying less than 0.4 V to this pin, the device will be turned off. Connect this pin to V
IN
if unused
Ground pin. For better thermal capability, directly connected to large ground plane
Input supply pin. Bypass this pin with a 1 µF ceramic or tantalum capacitor to ground
Output voltage. Connect C
OUT
between this pin and ground.
ERROR The open drain output is an error flag output which goes low when V
