250mA,Low Power Consumption LDO BL9103 Series

 Features
General Description



The BL9103 series are a group of positive voltage
output, three–pin regulator, that provide a high
current even when the input/output Voltage
differerntial is small. Low power consumption and
high accuracy is achieved through CMOS
technology. They allow input voltages as high as
18V.
Ultra low quienscent current: 3.0uA(typ)
High input voltage (up to 18v)
Low dropout voltage :[email protected]=40mA
(Vout=3.3v)
 Output voltage accuracy: ±2%
 Maximum output current:250mA
(within max.power dissipation,Vout=3.3V)
 Low temperature coefficient
 Package:SOT23-3、TO-92、SOT89-3

Note :
1. VOUT (T) :Specified Output Voltage
2.VOUT (E) :Effective Output Voltage ( ie. The output voltage when “VOUT (T)+1.0V”is provided at the Vin pin while
maintaining a certain Iout value.)
3.VDIF:VIN1 –VOUT (E)’
VIN1 :The input voltage when VOUT(E)’ appears as input voltage is gradually decreased.
VOUT (E)’=A voltage equal to 98% of the output voltage whenever an amply stabilized Iout and {VOUT
(T)+1.0V} is input.
