SN65DP159RGZ Description

Short technical summary and product information.

The Texas Instruments SN65DP159RGZ is an active ultra-low-dropout (LDO) voltage regulator designed for efficient power management. It can deliver up to 1.5A of output current with an input voltage range from 0.8V to 5.5V. The output voltage is adjustable, ranging from 0.8V to 3.6V, providing flexibility for different system requirements.

 

This LDO regulator features low noise (20 µVrms) and high Power Supply Rejection Ratio (PSRR) of 52 dB at 100 KHz, ensuring clean power delivery. It has a typical dropout voltage of 55mV at 1.5A, contributing to power efficiency. The device includes programmable soft-start functionality, an active high enable pin, and an open-drain power-good output.

 

The SN65DP159RGZ is stable with any output capacitor greater than or equal to 2.2µF. It operates over a wide temperature range of -40°C to 125°C. Available packages include VQFN (RGW), VQFN (RGR), and TO-263 (KTW), supporting surface mount applications.

 

Key features include 1% accuracy over line, load, and temperature, and excellent transient response. The device is suitable for applications requiring stable and low-noise power supply.
