BL9180

Dual,300mA Ultra-low Noise

CMOS LDO Regulator

FEATURES

DESCRIPTION



Up to 300mA Output Current(Each LDO)

The BL9180 dual, low noise, low-dropout regulator

supplying up to 300mA output current at each

channel. The output voltage for each regulator is set

independently by trimming. Voltages are selectable

in 50mV steps within a range of 1.2V to 3.3V by

operating from a 2V to 6V input. The BL9180

includes two independent logic-controlled shutdown

inputs and allows the output of each regulator to be

turned off independently. When both outputs

shutdown simultaneously, the chip will be turn off

and consumes nearly zero operation current which

is suitable for battery-power devices.

Dual Shutdown Pins Control Each Output

90uA Operating supply current per LDO

Excellent Line regulation:0.05%/V

Low Dropout:220mV@300mA

High Power Supply Rejection Ratio

Wide Operating Voltage Range:2.0V to 6.0V

1.2V to 3.3V Factory-Preset Output

High Accuracy: ±1% or ±2%

Internal Pulled down(8 MΩ)resistor

Current Limiting and Thermal Protection

Two LDOs in SOT-23-6 and ESOP-8 Package

RoHS Compliant and 100% Lead(Pb)-Free

The BL9180 includes high accuracy voltage

reference, error amplifier, current limit circuit and

output driver module.

APPLICATIONS



Cellular and Smart Phones

The BL9180 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 ±1% or

±2%. The BL9180 is available in SOT-23-6 and

ESOP-8 package which is Lead(Pb)-free.

Application hints:

Output capacitor (C_OUT≥2.2uF) is recommended

in BL9180 applications to assure the circuit’s

stability for output voltage ≤ 1.8V.
