TPL8151-S 1.5-A Wide-Input High-Current Low-Dropout Linear Regulator

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 range 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 package with guaranteed  operating temperature range from –40°C to +125°C.
