BELLING BL8559 2a linear regulator Datasheet

BL8559
2A Linear Regulator
GENERAL DESCRIPTION
FEATURES
BL8559 series are a group of positive voltage
output, high precise, 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.
•
•
•
•
•
•
•
BL8559 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%.
Low Quiescent Current: 26uA at 5V
High PSRR: 60dB range to 1KHz
Low Output Noise: 44uVRMS
Low Dropout: 430mV at 1.5A load
Maximum output current: 2.5A
Highly Accurate: ±2%
Low ESR Ceramic Capacitor Compatible
APPLICATIONS
