TPS78326DDCT

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

The TPS78326DDCT is a fixed-output low-dropout linear regulator from the Texas Instruments TPS783 series, housed in a SOT-23-5 thin package. It provides a fixed output voltage of 2.6 V with a maximum continuous output current of 150 mA. The device features an ultra-low quiescent current of 800 nA and supports an input voltage range up to 5.5 V. It includes integrated protection against overcurrent, thermal overload, and reverse polarity.

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

Verify the specific suffix DDCT corresponds to the cut-tape packaging format required for your assembly process. Confirm that the 2.6 V fixed output aligns with your system voltage requirements. Ensure the SOT-23-5 footprint matches your PCB layout constraints. Check RoHS compliance status if operating in regulated environments.

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

Select this component when a stable 2.6 V rail is needed with minimal static power draw. The TPS783 series offers superior noise performance compared to standard LDOs. Consider the 150 mA limit for load demands. The thin package is suitable for space-constrained designs. Verify input voltage does not exceed 5.5 V under all operating conditions.

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

This part belongs to the TPS783 family of ultra-low-power LDO regulators designed for portable applications. It shares architectural similarities with the TPS782 series but may differ in specific quiescent current specifications and temperature ranges. The TPS783 series emphasizes low noise and high PSRR for sensitive analog circuits.

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

Direct substitutes include other TPS783xx variants with different fixed output voltages (e.g., TPS78330) if voltage levels can be adjusted. Cross-series replacements like TPS782xx should be evaluated for pin compatibility and electrical parameter alignment.
