Description

The TPL910A is a series of 1-A high-current, 4.5-μVRMS

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

with only 500-mV maximum ultra-low dropout voltage at

1-A load current. The TPL910A series supports both fixed

output voltage ranging from 1.2 V to 5 V and adjustable

output voltage ranging from 0.8 V to 6 V with an external

resistor divider.

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

capability make the TPL910A series the ideal power

supply for noise-sensitive applications, such as highspeed

communication facilities, and high-definition imaging

equipment. Accurate output voltage tolerance, excellent

transient response, and adjustable soft-start control ensure

the TPL910A series optimal power supply for large-scale

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

and DSP.

The TPL910A series provides a small DFN3X3-8 package

with guaranteed operating temperature ranging from –

40°C to +125°C.
