BL8503

250mA CMOS Low Dropout Voltage Low consumption Regulator

Outline：

Features：

 Low Power Consumption：3.0uA（Typ.）

 Maximum Output Current： 250mA

 Small Dropout Voltage：

170mV@100mA (Vout=3.0V)

400mV@250mA (Vout=3.0V)

BL8503 series is a group of positive

voltage output, low power consumption, low

dropout voltage, three terminal regulator. It

can provide 250mA output current when

input / output voltage differential drops to

400mV（Vin =4.0V、Vout=3.0V）。The

very low power consumption of BL8503

（Iq=3.0uA）can greatly improve natural life

of batteries.

 Input Voltage Range：1.5V～10V

 Output Voltage Range：1.2V~6.0V

（customized on command in 0.1V steps）

BL8503 can provide output value in the

range of 1.2V~6.0V in 0.1V steps. It also can

customized on command.

 Highly Accurate：±2%(±1% customized）

 Output Current Limit

Applications：

BL8503 includes high accuracy voltage

reference, error amplifier, current limit circuit

and output driver module.

 Battery Powered equipment

 Power Management of MP3、PDA、DSC、

Mouse、PS2 Games

BL8503 has well load transient response

and good temperature characteristic, which

can assure the stability of chip and power

system. And it uses trimming technique to

guarantee output voltage accuracy within±

2%.

 Reference Voltage Source

 Regulation after Switching Power

BL8503 is available in SOT-89-3、SOT-

23-3,TO-92 packages which is lead free，it

also can available in these packages with

lead.

NOTE1：Input capacitor (Cin=1uF) is recommended in

all application circuit. Tantalum capacitor is

recommended.

NOTE2：Output capacitor (Cout=1uF) is recommended

in all application to assure the stability of

circuit. Tantalum capacitor is recommended.
