n PIN DESCRIPTIONS

SOT-23-5

PIN 1 : VIN

-

Power supply input pin. Bypass

with a 1

µF capacitor to GND

PIN 2 : GND -

Ground

pin.

This

also

functions

as

a

heatsink.

To

maximize power dissipation, use

of a large pad or the circuit-

board

ground

plane

is

recommended.

PIN 3 :

SHDN - Active-Low shutdown input pin.

PIN 4 : BP

- Noise bypass pin. An external

bypass capacitor connected to

the BP pin reduces noises at the

output.

PIN 5 : VOUT - Output pin. Sources up to 150

mA.

n DETAILED DESCRIPTION OF TECHNICAL TERMS

OUTPUT VOLTAGE (V

OUT)

The AIC1730 provides factory-set output voltages

from 1.8V to 3.3V, in 100mV increments. The output

voltage is specified with VIN = VOUT (TYP) + 1V and

IOUT = 0mA

DROPOUT VOLTAGE (V

DROP)

The dropout voltage is defined as the difference

between the input voltage and output voltage at

which point the regulator starts to fall out of

regulation. Below this value, the output voltage will

fall as the input voltage is reduced. It depends on the

load current and junction temperature. The dropout

voltage is specified at which the output voltage drops

100mV below the value measured with a 1V

difference.

CONTINUOUS OUTPUT CURRENT (I

OUT)

Normal rated output current. This is limited by

package power dissipation.
