Description

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 a thermal-enhanced DFN4X4-8

package with guaranteed operating temperature range

from −40°C to +125°C.
