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 1.25 V 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 thermal-enhanced DFN4x4-8, ESOP8, and SOT223-3 packages with guaranteed operating temperature range from –40°C to +125°C.
