TPL8151

1.5-A Wide-Input High-Current Low-Dropout Linear Regulator

Overview

The TPL8151 is a 1.5-A high-current, low-dropout linear regulator with up to 29-V wide input voltage range. The TPL8151 supports adjustable output voltage ranging from 1.25V with an external resistor divider and is stable with a 10-μF to 100-μF tantalum output capacitor.

The TPL8151 is compatible with older three-terminal adjustable linear regulators but has lower dropout voltage, tight output tolerance, and better transient performance.

The TPL8151 provides a thermal-enhanced DFN4X4-8 package with guaranteed operating temperature range from −40°C to +125°C.
