BL8552

BL8552
300mA Low Consumption Linear Regulator
GENERAL DESCRIPTION
FEATURES
BL8552 series are a group of positive
voltage output, highly 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.
•
•
•
•
•
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%
•
•
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%.
APPLICATIONS
