LR6156

Dual 300mA High PSRR LDO

FEATURES

DESCRIPTION

•

Two low dropout voltage regulators

300mA output current for each LDO

20uA operating supply current per LDO

Low 47uVRMS output noise

Standby Mode: 0.1uA

Low 160mV dropout at 300mA load

73dB PSRR at 100Hz

Excellent Line regulation: 0.05%/V

Independent Shutdown controls

1.5V to 4.5V Factory-Preset Output

Output Current Limit

The LR6156 is a dual,low-noise,low-

dropout regulator delivering at least 300mA of

continuous output current. The output voltage

for each regulator is set independently by

trimming.Voltages are selectable in 100mV

steps within a range of 1.5V to 4.5V.Typical

output noise is 47uVrms,and PSRR is 73dB

at 100Hz. The LR6156 includes two

independent logic-controlled shutdown inputs

and allows the output of each regulator to be

turned of independently.

High Accuracy: ±2% (±1% customized)

The LR6156 includes high accuracy

voltage reference, error amplifier, current limit

circuit and output driver module.

APPLICATIONS

•

Cellular phones

The LR6156 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%.

Cordless phones and radio

communication equipment

Battery Powered equipment

Notebook and hand-hold equipment

Wireless LAN

•

GPS receivers

The LR6156 is available in SOT-23-6

package which is lead(Pb)- free
