Linear Voltage Regulators

TLV70233DBVR Description

The TLV70233DBVR from Texas Instruments is a low-dropout (LDO) linear regulator designed for high-efficiency, low-power applications. It delivers a fixed 3.3V output with a maximum current of 300mA, making it ideal for space-constrained designs. Operating within an input voltage range of 2V to 5.5V, it features an ultra-low dropout voltage of 220mV (typical) and 375mV (max) at full load, ensuring stable performance even with minimal headroom. The device boasts ±0.5% output voltage accuracy, 68dB PSRR (typical), and a quiescent current of just 35µA, optimizing efficiency for battery-powered systems. Packaged in a 5-pin SOT-23 (DBV) tape-and-reel format, it is optimized for surface-mount PCB designs.

TLV70233DBVR Features

• High Accuracy & Efficiency: ±0.5% voltage regulation and low dropout (220mV typ) enhance power efficiency.
• Robust Protection: Integrated current limit and thermal shutdown safeguard against overloads.
• Low Noise & High PSRR: 68dB ripple rejection minimizes noise in sensitive analog/digital circuits.
• Wide Operating Range: Supports 2V–5.5V input, compatible with Li-ion, 3.3V, and 5V rails.
• Compact & Lightweight: SOT-23-5 package (3.05mm × 1.75mm × 1.1mm) suits portable and IoT devices.
• Low Quiescent Current: 35µA extends battery life in always-on applications.

TLV70233DBVR Applications

• Portable Electronics: Smartphones, wearables, and wireless sensors benefit from its low Iq and small footprint.
• IoT & Edge Devices: Reliable voltage regulation for MCUs, RF modules, and sensors in 3.3V systems.
• Industrial Controls: Stable supply for PLCs, transducers, and low-power actuators (up to 125°C).
• Automotive Accessories: Non-automotive grade but suitable for infotainment/peripheral circuits.
• Medical Devices: Precision voltage delivery for diagnostic tools and portable monitors.

Conclusion of TLV70233DBVR

The TLV70233DBVR excels in power-sensitive, compact designs requiring high accuracy and low noise. Its best-in-class dropout voltage, PSRR, and protection features make it superior to generic LDOs, while the SOT-23 package ensures easy integration. Ideal for battery-operated and noise-sensitive systems, it balances performance, size, and cost—making it a top choice for modern embedded and portable applications.
