Description

The TPL9218 product is a 2-A high-current, 6-μV RMS

low-noise, high-PSRR, and high-accuracy linear regulator

with a typically 80-mV ultra-low dropout voltage in the 2-A

load condition. The TPL9218 product supports 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 TPL9218 product 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 TPL9218 product an optimal power supply for largescale processors and digital loads, such as CPU, ASIC,

FPGA, CPLD, and DSP.

The TPL9218 product provides a 10-pin 2.5×2.5 DFN

package with guaranteed operating junction temperature

ranging from ?40°C to +125°C.
