TPS71334DRCR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPS71334DRCR is a dual low-dropout linear voltage regulator from Texas Instruments, housed in a 10-pin VSON (3x3 mm) package. It integrates two independent regulators: one fixed at 3.3V and one adjustable output ranging from 1.2V to 5.5V. Each channel delivers up to 250mA of output current with ultra-low noise characteristics and high power supply rejection ratio (PSRR). The device operates with an operating supply current of 300µA and has a maximum power dissipation of 1.92W. The reference voltage is specified at 1.225V.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Dual independent LDO channels providing separate fixed and adjustable outputs for flexible power distribution
• Ultra-low noise performance designed for sensitive RF and analog applications
• High power supply rejection ratio (PSRR) to minimize ripple and noise coupling

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• RF front-end modules needing low-noise regulation for signal integrity
• Portable devices utilizing space-constrained VSON packaging

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'DRCR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 10-VSON (3x3) footprint matches the PCB design guidelines provided in the official datasheet. Ensure thermal management strategies account for the 1.92W power dissipation rating under expected load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when dual isolated rails are necessary within a single package to save board space. The fixed 3.3V output simplifies logic level interfacing, while the adjustable rail allows customization for varying core voltage requirements. Consider the 300µA quiescent current impact on overall system efficiency during light-load operations compared to switching alternatives.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the TPS713xx family of high-performance RF LDOs tailored for noise-sensitive applications. The series emphasizes low noise and high PSRR, distinguishing it from standard general-purpose regulators. The DRCR variant specifically denotes the reel-packaged version of the dual-channel regulator, ensuring compatibility with surface-mount technology production lines.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for direct pin-compatible substitutes within the TPS713xx family, such as the TPS71319, if different output configurations are acceptable. Verify that any replacement maintains the 250mA per channel current capability and the 10-VSON package dimensions to ensure mechanical interchangeability without redesigning the PCB layout.
