300mA High PSRR, Fast Response Linear Regulator
FEATURES
DESCRIPTION
BL8067 series is a group of positive voltage
output, low power consumption, low dropout
voltage regulator.
Low Power Consumption: 50uA (Typ.)
Low output noise (47uVRMS)
Standby Mode: 0.1uA
Low dropout Voltage:
BL8067 can provide output value in the range of
1.0V~4.5V every 0.1V step. It also can be
customized on command.
210mV@Iout=300mA,Vout=3V
High Ripple Rejection: 68dB@1KHz (Typ.)
Low Temperature Coefficient: ±100ppm/C
Excellent Line regulation: 0.05%/V
Build-in chip enable and discharge circuit
Output Voltage Range: 1.0V~4.5V
(customized on command every 0.1V step)
Highly Accurate: ±2%
BL8067 includes high accuracy voltage reference,
error amplifier, current limit circuit and output
driver module with discharge capability.
BL8067 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%.
