BL8568G

500mA High PSRR, Fast Response Linear Regulator

DESCRIPTION

FEATURES

BL8568G series is a group of positive voltage

output, low power consumption, low dropout

voltage regulators.

•

Low power consumption: 60uA (Typ.)

Standby mode: 0.1uA

Low dropout voltage:

330mV @I_OUT=500mA, V_OUT=3.3V (Typ.)

High PSRR: 70dB@1KHz (Typ.)

Low temperature coefficient: ±100ppm/C

Excellent line regulation: 0.05%/V

Output voltage range: 0.9V~3.6V

Highly accurate: ±2%

Build-in chip enable and discharge circuit

Thermal shutdown

Overcurrent protection

BL8568G can provide output value in the range of

0.9V~3.6V every 0.1V step. It also can be

customized on command.

•

BL8568G includes high accuracy voltage reference,

error amplifier, current limit circuit and output

driver module with discharge capability.

BL8568G 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

BL8568G is available in SC70-5, SOT23-3, SOT23,

SOT23-5 and DFN1x1-4 packages, which are

lead(Pb)-free.

•

Power source for cellular phones and various

kinds of PCSs

Battery powered equipment

Power management of MP3, PDA, DSC, mouse,

PS2 games

•

Reference voltage source

•

Regulation after switching power
