DESCRIPTION
AIC1747 is optimized for ceramic capacitor
operation with 300mA continuous current. The
AIC1747 is designed for portable RF and wireless
applications with demanding performance and
space requirements.
The AIC1747 offers high precision output voltage
of 2% tolerance. Output Voltage is available
within 1.1~4.2V. There are version of 1.1, 1.2, 1.3,
1.5, 1.8, 2.5, 2.7, 2.8, 2.85, 3.0, 3.3, 3.5, 3.7, 3.8
and 4.0 for a fixed output voltage.
A noise bypass pin is available for further
reduction of output noise. At 300mA load current,
a 270mV dropout can be performed. The quality
of low quiescent current and low dropout voltage
makes the device ideal for battery power
applications. The high ripple rejection and low
noise of the AIC1747 provide enhanced
performances for critical applications such as
cellular phones, and PDAs.
In addition, a logic-level shutdown input is
included, which reduce supply current to less than
0.01μA (typ.) in shutdown mode with fast turn-on
& off time less than 50 μ s & 30 μ s. The
AIC1747’s current limit and thermal protection
provide protection against any overload condition
that would cause excessive junction temperatures.
