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.
