TPS75401QPWPR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPS75401QPWPR is a high-performance, low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It features Fast-Transient Response technology and delivers a continuous output current of 2 A. The device supports an adjustable output voltage range from 1.5 V to 5 V with a single output configuration. Key electrical specifications include a maximum dropout voltage of 210 mV at full load, a line regulation of 0.01 %/V, and a load regulation of 1 mV. The quiescent current is specified at 70 uA, while the total static current reaches 125 uA. It operates within a junction temperature range of -40°C to +125°C and utilizes an HTSSOP-20 surface-mount package.
