Description

The TPL8032 series of products are 300-mA high PSRR,

ultra-low noise, and low-dropout linear regulators with a

20-V wide input voltage range. The TPL8032 series of

products support both adjustable output voltage ranging

from 1.22 V to 18 V with an external resistor divider

and fixed output voltage ranging from 1.5 V to 5 V. The

TPL8032 series of products are stable with a 2.2-μF to

100-μF ceramic output capacitor.

The TPL8032 series of products have high PSRR with

79 dB at 1 kHz and 5.68 μVRMS ultra-low noise. These

features make the TPL8032 series suitable for noisesensitive applications, such as high-performance analog

devices or high-definition imaging equipment, to suppress

the large ripple and noise generated from the previous

stage power supply. Besides, output short-circuit protection

and thermal protection features improve the system

reliability under multiple operating conditions.

The TPL8032 series provides the SOT23-5 package with

a guaranteed junction temperature range from –40°C to

+125°C.
