TPS78326DDCR TI Low-Dropout Regulator | SOT-23-THIN | 200mA, 3.3V Output

Product Overview

The TPS78326DDCR from Texas Instruments is a low-dropout (LDO) linear regulator designed for power-sensitive applications. It offers a fixed output voltage of 3.3V with a maximum output current of 200mA. Housed in a compact SOT-23-THIN package, this device is ideal for space-constrained designs requiring low quiescent current and high power-supply rejection ratio (PSRR). The TPS78326DDCR features a low dropout voltage of typically 150mV at full load, enabling efficient operation even with small input-to-output voltage differentials. Its ultra-low quiescent current of 1µA (typical) makes it suitable for battery-powered devices, extending operational life. The device also includes overcurrent and thermal shutdown protection for robust performance.
