AIC1737
LOW OUTPUT VOLTAGE, 300mA LOW DROPOUT LINEAR REGULATOR
SPEC NO: DS-1737-00 08/06/00
PIN DESCRIPTION
VOUT PIN - Output pin.
GND PIN - Power GND.
VIN PIN - Power Supply Input.
APPLICATION INFORMATIONS
A 1µF (or greater) capacitor is required between the
AIC1737 output and ground for stability. Without this
capacitor the part will oscillate. Even though most
types of capacitor may work, the equivalent series
resistance (ESR) should be held to 5Ω or less if
Aluminum electrolytic type is used. Many Aluminum
electrolytics have electrolytes that freeze at about
-30°C, so solid tantalums are recommended for
operation below -25°C. The value of this capacitor
may be increased without limit.
A 0.1µF capacitor (or greater) should be placed from
the AIC1737 input to ground if the lead inductance
between the input and power source exceeds 500nH
(approximately 10 inches of trace).
