Ultra-Low Quiescent Current 3.3V Linear Voltage Regulator IC for Battery-Powered Applications (SOT-23-5 Package)
The TPS78233DDCR is a fixed 3.3V linear voltage regulator IC designed to deliver stable output with load current capability up to 150mA. Engineered for ultra-low quiescent current operation, it is particularly suitable for battery-powered and energy-efficient applications where extended battery life is critical. The device ensures reliable voltage regulation for microcontrollers, wireless modules, sensors, and low-power logic circuits operating on a 3.3V rail.
Packaged in a compact SOT-23-5 surface-mount form factor, this regulator enables space-saving PCB designs while maintaining consistent electrical performance. Its low-dropout characteristics allow stable output even when the input voltage is close to the regulated 3.3V level, making it well suited for portable electronics, IoT devices, and embedded control systems.
