Description
The TPL8032Q product is a 300-mA high PSRR, ultra-low
noise, low dropout linear regulator with 20-V wide input
voltage range. The TPL8032Q product supports adjustable
output voltage ranging from 1.22 V to 18 V with an
external resistor divider and is stable with a 2.2-μF or
larger ceramic output capacitor.
The TPL8032Q product features high PSRR with 96 dB
at 1 kHz and 5.2-μVRMS ultra-low noise. These features
make the TPL8032Q product suitable for noise-sensitive
applications with large ripple and noise generated from the
previous stage power supply, such as high-performance
analog devices or high-definition imaging equipment. The
output shortage protection and thermal overload-protection
circuits improve the reliability under heavy load conditions.
The TPL8032Q product provides a thermal-enhanced
ESOP8 package with guaranteed operating ambient
temperature ranging from −40°C to +125°C.
