AQT104
Quik LDO
2.5V or Adjustable, No Output Cap, Low Dropout Regulator
Preliminary Design Specification
Revision 0.5, May 2, 2003
General Description
The Quik LDO™ AQT104 is a low
dropout regulator that requires no
external output capacitor for stability and
it is stable with any capacitive load. It
offers 0.5 Ohms pass device with 500mA
load current. Its output voltage is preset
to values between 2V and 3.3V with 1%
accuracy and presents very good line
and load regulation. It also includes
output current limit with foldback
characteristic and thermal shutdown. The
removal of the output capacitor allows
cost and board space reduction along
with energy saving at power on and off.
It is best suited for battery-powered
equipments and in particular for cellular
phones.
Applications
• Cordless and cellular phones
• Medical equipment
• PDAs and battery-powered equipments
