BL8567
300mA, Wide Input Voltage, Low Consumption Linear Regulator
GENERAL DESCRIPTION
BL8567 series are a group of positive voltage
output, high precise, and high PSRR and low
power consumption voltage regulator.
Voltages are selectable in 100mV steps
within a range of 2.5V to 5.5V. It also can be
customized on command.
BL8567 series have 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%.
BL8567 series are available in SOT-23-3,
SOT-23-5,SOT-89-3 packages, which are
lead (Pb)- free.

TYPICAL APPLICATION
Note 1: Input capacitor (CIN=1uF) is
recommended in all applications.
Note 2: Output capacitor (COUT=1uF/6.8uF) is
recommended in all applications to assure the
stability of circuit. 1uF Tantalum capacitor or
6.8uF ceramic capacitor is recommended.
