A6250A
LOW DROPOUT VOLTAGE REGULATOR
250mA LOW CONSUMPTION LINEAR REGULATOR
DESCRIPTION
FEATURES
A6250A series is a group of positive voltage output, Low Power Consumption:1.0uA(Typ.
low power consumption, low dropout voltage, three Maximum Output Current:250mA
terminal regulator. It can provide 250mA output
current when input / output voltage differential drops
to 430mV (VOUT=2.8V). The very low power
consumption of A6250A (IQ=1.0uA) can greatly
improve natural life of batteries.
A6250A can provide output value in the range of
1.1V~5.5V in 0.1V steps. It also can customized on
command.
A6250A includes high accuracy voltage reference,
error amplifier, current limit circuit and output driver
Small Dropout Voltage
210mV@100mA (VOUT=2.8V)
430mV@250mA (VOUT=2.8V)
Input Voltage Range:1.5V~8V
Output Voltage Range:1.1V~5.5V
(customized on command in 0.1V steps)
Highly Accurate:±2%(±1% customized)
Output Current Limit
Available in SOT-23 and SOT-89-3 Packages
module.
APPLICATION
A6250A has well load transient response and good
temperature characteristic, and it uses trimming
technique to guarantee output voltage accuracy
within±2%.
The A6250A is available in SOT-23 and SOT-89-3
packages.
