Linear & Switching Voltage Regulators

TPS70933DBVR Description

The TPS70933DBVR from Texas Instruments is a 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 at 150mA) ensure stable operation even under varying supply conditions. Packaged in a compact SOT23-5 form factor, it is optimized for surface-mount designs requiring minimal board space.

TPS70933DBVR Features

• Ultra-Low Quiescent Current: 2.05 µA (typical) extends battery life in portable devices.
• High PSRR: 80dB at 10Hz to 52dB at 1kHz ensures noise suppression for sensitive analog/digital circuits.
• Robust Protection: Includes over-current, over-temperature, reverse current protection, and UVLO for enhanced reliability.
• Enable Control: Allows power sequencing and shutdown to minimize standby power consumption.
• Wide Input Range: Supports up to 30V, accommodating unstable or unregulated supplies.
• Low Dropout: 1.4V at full load maximizes efficiency in low-voltage applications.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.

TPS70933DBVR Applications

• Battery-Powered Devices: IoT sensors, wearables, and handheld instruments benefit from its low Iq.
• Industrial Systems: Provides stable voltage for PLCs, sensors, and control modules with high PSRR.
• Automotive Electronics: Suitable for infotainment, ADAS, and low-power ECUs due to wide input tolerance.
• Consumer Electronics: Ideal for smart home devices, audio equipment, and peripherals requiring minimal noise.
• Medical Devices: Ensures reliable power for portable monitors and diagnostic tools with robust protection.
