LOW DROPOUT VOLTAGE REGULATOR
DUAL 500mA HIGH PSRR LINEAR REGULATOR
DESCRIPTION
FEATURES
A6505 dual, low-noise, low-dropout regulator delivers
at least 500mA of continuous output current. The
output voltage for each regulator is set independently
by trimming. Voltages are selectable in 100mV steps
within a range of 1.2V to 4.5V. The A6505 includes
two independent logic-controlled shutdown inputs and
allows the output of each regulator to be turned of
independently.
Two low dropout voltage regulators
500mA output current for each LDO
Low output noise (50uVRMS
)
Low dropout Voltage:0.08V@150mA(Typ.)
Standby Mode: 0.1uA
High Ripple Rijection:72dB@1KHz (Typ.)
Excellent Line regulation: 0.05%/V
Independent Shutdown controls
1.2V to 4.5V Factory-Preset Output
Output Current Limit
A6505 includes high accuracy voltage reference, error
amplifier, current limit circuit and output driver module.
Highly Accurate: ±2%
Available in SOT-26 package.
A6505 has excellent load and line transient response
and good temperature characteristics, which can
assure the stability of chip and power system. And it
uses trimming technique to guarantee output voltage
accuracy within ±2%.
