PIN 1 : VIN - Power supply input pin. Bypass
with a 1
μ
F capacitor to GND
PIN 2 : GND - Ground pin.
PIN 3 :
SHDN
- Active-Low shutdown input pin.
PIN 4 : BP
- Noise bypass pin. An external
bypass capacitor connected to
BP pin reduces noises at the
output.
PIN 5 : VOUT - Output pin. Sources up to 500
mA.
DROPOUT VOLTAGE (V
DROP
)
The dropout voltage is defined as the difference
between the input voltage and output voltage at
which the output voltage drops 100mV. Below
this value, the output voltage will fall as the input
voltage reduces. It depends on the load current
and junction temperature.
LINE REGULATION
Line regulation is the ability of the regulator to
maintain a constant output voltage as the input
voltage changes. The line regulation is specified
as the input voltage changes from V
IN
= V
OUT
+
1V to V
IN
= 7V and I
OUT
= 1mA.
LOAD REGULATION
Load regulation is the ability of the regulator to
maintain a constant output voltage as the load
current changes.
A pulsed measurement with an
input voltage set to V
IN
= V
OUT
+ V
DROP
can
minimize temperature effects.
The load regulation
is specified by the output current ranging from
0.1mA to 500mA.
