BL8565
REV1.0-Revised DEC 2007
500mA High PSRR, Low Dropout Voltage Linear Regulator
DESCRIPTION
FEATURES
BL8565 series is a group of positive voltage
output, low noise,low power consumption, low
dropout voltage regulator.
•
•
•
BL8565 can provide output value in the range
of 1.5V~4.5V every 0.1V step. It also can be
customized on command.
•
BL8565 includes high accuracy voltage
reference, error amplifier, current limit circuit
and output driver module with discharge
capability.
•
•
•
BL8565 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%.
