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 μV
RMS
ultra-low noise. These
features make the TPL8032 series suitable for noise-
sensitive 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.
