Mingjiada Electronics Supply TI TPS7A6550 300mA, 40V Automotive Low-Dropout Voltage Regulator

TPS7A6550 is a 300mA, 40V input, ultra-low quiescent current low-dropout linear regulator (LDO) developed by Texas Instruments (TI) for automotive electronics, featuring a fixed 5V output with an output accuracy of ±2 per cent, with a typical light-load quiescent current of just 25 µA. It is AEC-Q100 certified for automotive applications and operates at a maximum junction temperature of 150°C. Shenzhen Mingjiada Electronics Co., Ltd. — long-term supplier of the TPS7A6550QKVURQ1 (TO-252-3 package, brand-new and genuine in stock) and the full range of TI power management devices, supporting both sample and bulk purchases.

TPS7A6550 low-dropout linear regulator is specifically designed to meet the requirements for low power consumption and a quiescent current of less than 25 µA in light-load applications. The device features integrated overcurrent protection, and its design ensures stable operation even when using low-ESR ceramic output capacitors. The low-voltage tracking capability allows for the use of smaller input capacitors and may eliminate the need for a boost converter during cold start-up.
