TPS70245PWP

TPS70245PWP Description

The TPS70245PWP from Texas Instruments is a dual-output, low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. This 20-pin HTSSOP-packaged IC delivers fixed outputs of 3.3V and 1.2V with respective current capacities of 500mA and 250mA, making it ideal for multi-voltage systems. Operating with an input voltage range up to 6V, it features ultra-low quiescent current (190 µA) and supply current (230 µA max), enhancing efficiency in battery-powered designs. Its 60dB PSRR (1kHz) ensures excellent noise rejection, critical for sensitive analog/digital circuits.

TPS70245PWP Features

• Dual Outputs: Independent 3.3V/500mA and 1.2V/250mA regulators with sequencing support for controlled power-up.
• Advanced Control & Protection: Integrated enable, power-good, reset, and sequencing functions, plus over-current, over-temperature, reverse-polarity, and UVLO protection.
• High Efficiency: Low dropout and quiescent current minimize power loss.
