BL8552
300mA Low Consumption Linear Regulator
GENERAL DESCRIPTION
BL8552 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 1.2V to 3.6V. It also can be
customized on command.
BL8552 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%.
BL8552 series are available in SOT-23-3,
SOT-23-5, SOT-89-3 and TO-92 packages,
which are lead (Pb)- free.
FEATURES
Low Quiescent Current: 2uA at 5V
60dB PSRR at 100Hz
Low Output Noise: 44uVRMS
Low Dropout: 280mV at 150mA load
Low Temperature Coefficient: ±100ppm/C
Excellent Line Regulation: 0.05%/V
Highly Accurate: ±2%
APPLICATIONS
Reference Voltage Source
Battery Powered Equipment
Hand-Hold Equipment
Wireless LAN
GPS Receivers

Note 4: The maximum power rating of each package is a constant, so along with the change of ILOAD, the
VDD-VOUT should be controlled to a certain range to ensure the normal operation.
