TPS78330DDCT

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

The TPS78330DDCT is a fixed-output low-dropout linear regulator from the Texas Instruments TPS783xx series. It provides a stable 3V output with a maximum load current of 150mA. The device operates within an input voltage range of 2.2V to 5.5V and features a typical quiescent current of 800nA. It utilizes a SOT-23-5 thin package for surface-mount installation. The regulator includes protection mechanisms against overcurrent, thermal overload, and reverse polarity. It supports an operating temperature range from -40°C to +105°C.

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

Verify the specific suffix DDCT corresponds to the SOT-23-5 Thin package and Cut Tape or Reel packaging format as listed by authorized distributors. Confirm RoHS compliance status and Moisture Sensitivity Level (MSL) ratings prior to integration into manufacturing processes. Ensure the supplier source is an authorized Texas Instruments partner to guarantee component authenticity and traceability.

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

Select this component when a fixed 3V rail is required with minimal ground current draw. The 150mA output capability suits moderate load scenarios. Consider the 800nA quiescent current for efficiency optimization. Verify that the input voltage remains above the minimum dropout threshold across the full load and temperature range. The SOT-23-5 package is appropriate for compact PCB layouts.

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

This part belongs to the TPS783xx family of ultra-low IQ LDO regulators designed for portable applications. It shares architectural similarities with the TPS782xx series but offers specific performance characteristics tailored for cost-sensitive and space-constrained designs. The TPS78330 variant specifically targets 3V output requirements within the standard 2.2V to 5.5V input window.

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

Compatible substitutes include TPS78330DDCR (Reel packaging variant) and TPS78330DRVR (different package option). Cross-reference electrical parameters such as quiescent current and dropout voltage to ensure functional equivalence.
