BL9118
800mA Adjustable Voltage High Speed LDO Regulators BL9118 Series
General Description
The BL9118 series are highly accurate, low noise,
LDO Voltage Regulators that are capable of
providing an output current that is in excess of
800mA with a maximum dropout voltage of 1.0V at
800mA（BL9118-1.8V）.This series contains three
fixed output voltages of 1.2V,1.8 V and 2.5V that
have no minimum load requirement to maintain
regulation. On chip trimming adjusts the
reference/output voltage to within ±2% accuracy.
Internal protection features consist of output
current limiting, safe operating area compensation,
and thermal shutdown. The BL9118series can
operate with up to 15 V input. Devices are available
in SOT223.

Note ：
1. VOUT (T) ：Specified Output Voltage
2.VOUT (E) ：Effective Output Voltage ( ie. The output voltage when “VOUT (T)+1.2V”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)+1.2V} is input.
