Description

The TPL9208 series of products are 2-A high-current,

3.3-μVRMS low-noise, high-PSRR, high-accuracy linear

regulators with typically 150-mV ultra-low dropout voltage

at 2-A load condition. The TPL9208 series of products

support 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 external resistor dividers.

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

capabilities make the TPL9208 series 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 flexible soft-start control ensure

the TPL9208 series an optimal power supply for largescale

processors and digital loads, such as CPU, ASIC,

FPGA, CPLD, and DSP.

The TPL9208 series of products provide 10-pin

DFN2.5X2.5 and 20-pin QFN5X5 packages with

guaranteed operating junction temperature ranging from

−40°C to +125°C.
