Description

Adjustable Output Voltage: 0.8 V to 5.2 V

The TPL9308 is a 3-A high-current, 4-μV_RMSlow-noise,

high-PSRR, high-accuracy linear regulator with maximum

300-mV ultra-low dropout voltage at 3-A load condition.

The TPL9308 supports both fixed output voltage ranging

from 0.8 V to 3.95 V and adjustable output voltage ranging

from 0.8 V to 5.2 V with an external resistor dividers.

±1% Output Accuracy over Line Regulation, Load

Regulation, and Operating Temperature Range With

BIAS

3-A Maximum Output Current

Low Dropout Voltage: 300 mV Maximum at 3 A

High PSRR:

•

Ultra-low noise, high PSRR, and high-output-current

capabilities make the TPL9308 an ideal power supply

for noise-sensitive applications, such as high-speed

communication facilities, test and measurement devices,

or high-definition imaging equipment. Accurate output

voltage tolerance, output voltage remote sensing, excellent

transient response, and adjustable soft-start control ensure

the TPL9308 an optimal power supply for the large-scale

processors and digital loads, such as ASIC, FPGA, CPLD,

and DSP.
