BL8568

500mA High PSRR, Linear Regulator, w. Output Discharge

DESCRIPTION

FEATURES

BL8568 series is a group of positive voltage

output, low power consumption, low dropout

voltage regulator.

 Output voltage range: 1.0V~4.5V (customized

on command every 0.1V step)

 Low power consumption: 35uA (Typ.)

 Low output noise (47uVRMS)

BL8568 can provide output value in the range of

1.0V~4.5V every 0.1V step. It also can be

customized on command. BL8568 can also work

under a wide input voltage ranging from 2.0V to

6V.

 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%

BL8568 includes high accuracy voltage reference,

error amplifier, current limit circuit and output

driver module.

 Output current limit

 Fold-back output short circuit protection

BL8568 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



Power source for cellular phones and various

kind of PCSs



Battery Powered equipment

Power Management of MP3, PDA, DSC,

Mouse, PS2 Games

BL8568 is available in SOT-23-3, SOT-23-5, SC-70-5

and DFN1x1-4 packages which is lead free.



Voltage Reference
