BL8061
250mA Low Consumption Linear Regulator
DESCRIPTION
BL8061 series is a group of positive voltage
output, low power consumption, low dropout
voltage, three terminal regulator. It can provide
200mA output current when input / output
voltage differential drops to 420mV （ Vout=
3.3V）, And it also provides foldback short-
circuit protection and output current limit
function. The very low power consumption of
BL8061（Iq=2.0uA）can greatly improve natural
life of batteries.
BL8061 can provide output value in the range of
1.1V~5.0V in 0.1V steps. It also can customized
on command.
BL8061 includes high accuracy voltage reference,
error amplifier, current limit circuit and output
driver module.
BL8061 has well load transient response and
good temperature characteristic, And it uses
trimming technique to guarantee output voltage
accuracy within±2%.
