BL8591
100mA High PSRR, Fast Response Linear Regulator
DESCRIPTION
BL8591 series is a group of positive voltage
output, low power consumption, low dropout
voltage regulator.
BL8591 can provide output value in the range
of 1.2V~4.5V every 0.1V step. It also can be
customized on command.
BL8591 includes high accuracy voltage
reference, error amplifier, current limit circuit
and output driver module with discharge
capability.
BL8591 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%.
BL8591 is available in SOT23-3, SOT23-5,
SOT89-3, SOT89-5 and TO92 packages
which are lead free. It also can available in
these packages with lead.
TYPICAL APPLICATION
BL8591
NOTE: Input capacitor (Cin=1uF) and Output
capacitor (Cout=1uF/2.2uF) are
recommended in all application circuit.
