300mA Linear Regulator
 ^DESCRIPTION
The AIC1952 is a dual output linear regulator
in a tiny SOT-23-6, DFN 6L-2X2 package. It is
optimized for low ESR ceramic capacitors
operation and up to 300mA continuous current
on each output.
The AIC1952 offers high precision output
voltage of 2%. At 300mA load current, a
200mV dropout is performed when output
voltage is equal to 3.3V. The quality of low
quiescent current and low dropout voltage
makes this device ideal for battery power
applications. The high ripple rejection and low
noise of the AIC1952 provide enhanced
performances for critical applications such as
cellular phones, and PDAs.
The AIC1952 includes current limit and thermal
shutdown protection. Each of the output is
controlled independently.
