Linear & Switching Voltage Regulators

TPS709A33DBVT Description

The TPS709A33DBVT 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 150mA of output current with an ultra-low quiescent current of 2.05 µA, making it ideal for battery-powered and energy-efficient systems. Its wide input voltage range (up to 30V) and low dropout voltage (1.4V @ 150mA) ensure stable operation even under varying load conditions. Packaged in a compact SOT23-5 form factor, it is optimized for surface-mount designs requiring minimal board space.

TPS709A33DBVT Features

• Ultra-Low Quiescent Current: 2.05 µA enhances battery life in portable applications.
• High PSRR: 80dB @ 10Hz to 52dB @ 1kHz ensures excellent noise rejection for sensitive analog/digital circuits.
• Robust Protection: Integrated safeguards include over-current, over-temperature, reverse current, and UVLO (Under Voltage Lockout).
• Enable Control: Allows for power sequencing and standby mode, reducing power consumption during idle states.
• Wide Input Range: Supports up to 30V, accommodating diverse power sources.
• Low Dropout: 1.4V @ 150mA minimizes power dissipation, improving efficiency.
• RoHS3 & REACH Compliant: Environmentally friendly and suitable for global markets.
