Linear & Switching Voltage Regulators

TPS73033DBVT Description

The TPS73033DBVT from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. This fixed-output (3.3V) regulator delivers up to 200mA of output current with an ultra-low dropout voltage of 0.21V (max) at 200mA, ensuring efficient operation even with tight input-to-output differentials. Its input voltage range extends up to 5.5V, making it suitable for battery-powered and low-voltage systems. The device features a low quiescent current of 250 µA, enhancing energy efficiency in always-on applications. Packaged in a compact SOT23-5 form factor, it is ideal for portable and embedded designs.

TPS73033DBVT Features

• High PSRR (68dB at 100Hz): Minimizes noise for sensitive analog/digital loads.
• Advanced Protection: Includes over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) for robust system reliability.
• Enable Control: Allows dynamic power management via an external logic signal.
• Low Dropout (0.21V at 200mA): Maximizes efficiency in low-headroom scenarios.
• RoHS3 & REACH Compliant: Meets stringent environmental standards.
• Wide Operating Range: Supports input voltages from 2.7V to 5.5V, accommodating Li-ion, USB, or 3.3V/5V rail inputs.

TPS73033DBVT Applications

• Portable Electronics: Smartphones, wearables, and IoT devices benefit from its compact size and low Iq.
• Embedded Systems: Ideal for microcontrollers (MCUs), sensors, and FPGAs requiring stable 3.3V rails.
• Battery-Powered Devices: Extends battery life in medical devices, handheld instruments, and wireless modules.
• Noise-Sensitive Analog Circuits: Audio amplifiers, ADCs, and RF components leverage its high PSRR.

Conclusion of TPS73033DBVT

The TPS73033DBVT stands out as a versatile, high-efficiency LDO regulator, combining low dropout, excellent noise rejection, and robust protection features in a miniature package. Its ability to operate with minimal headroom and quiescent current makes it a superior choice for power-sensitive and space-constrained designs. Whether for consumer electronics, industrial systems, or battery-operated applications, this regulator delivers reliable performance while adhering to environmental and safety standards.
