TLV70433DBVR – 150mA Low-Dropout (LDO) Voltage Regulator – Detailed Overview
The TLV70433DBVR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for low-power, high-precision applications. It delivers a fixed 3.3V output with a 150mA maximum current, making it ideal for battery-powered and space-constrained systems. With an ultra-low dropout voltage of 175mV (typical at 150mA load), it ensures stable operation even with input voltages close to the output. The device features low quiescent current (17µA typical), enhancing efficiency in always-on applications. Packaged in a SOT-23-5 (DBV) form factor, it supports compact PCB designs while offering thermal shutdown and current-limit protection for reliability.
Key Features
● Fixed 3.3V output with ±2% accuracy over temperature.
● Ultra-low dropout (175mV at 150mA) for extended battery life.
● Low noise (32µV RMS) and high PSRR (70dB at 1kHz) for sensitive analog circuits.
● Wide input range (2V to 6V), compatible with Li-ion and 3V/5V rails.
● Stable with tiny 1µF ceramic capacitors, reducing BOM cost.
3.3V LDO regulator Applications
The TLV70433DBVR is widely used in portable electronics, IoT sensors, wearable devices, and battery management systems. Its precision and low power consumption suit medical devices, wireless modules, and microcontroller power supplies. The high PSRR makes it ideal for RF/analog circuits where noise immunity is critical.
