BL8563

BL8563
300mA High PSRR, Linear Regulator, w. Output Discharge
DESCRIPTION
FEATURES
BL8563 series is a group of positive voltage
output, low power consumption, low dropout
voltage regulator.
 Input voltage range: 1.5 – 6V
 Output voltage range: 1.0V~4.5V (customized
on command every 0.1V step)
 Low power consumption: 35uA (Typ.)
 Low output noise (47uVRMS)
 Shutdown mode: 0.1uA
 Low dropout voltage: 300mV@300mA (Typ.)
 High ripple rejection:70dB@1KHz (Typ.)
 Low temperature coefficient: ±100ppm/C
 Excellent line regulation: 0.05%/V
 Build-in 1.5K discharge resistor when CE low
 Highly accurate: ±2%
 Output current limit
 Fold-back output short circuit protection
BL8563 can provide output value in the range of
1.0V~4.5V every 0.1V step. It also can be
customized on command. BL8563 can also work
under a wide input voltage ranging from 1.5V to
6V.
BL8563 includes high accuracy voltage reference,
error amplifier, current limit circuit and output
driver module.
BL8563 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%.
APPLICATIONS
BL8563 is available in SOT-23-3, SOT-23-5, SC-70-5
and DFN1x1-4 packages which is lead free.
