Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for TPS76338DBVR

TPS76338DBVR

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

The TPS76338DBVR is a fixed-output low-dropout linear voltage regulator from the Texas Instruments TPS763 family. It provides a nominal output voltage of 3.8V with a maximum load current capability of 150mA. The device operates within an input voltage range of 2.7V to 10V and features a typical dropout voltage of 175mV at full load. Quiescent current is specified at 65µA (typical) at no load, rising to 765µA at 150mA load. It includes thermal shutdown and overcurrent protection, housed in a 5-pin SOT-23 package.

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

Logic-enabled sleep mode reduces quiescent current to 1µA maximum when disabled.
Internal soft-start circuit limits inrush current during startup for smaller input capacitance requirements.
Active over-shoot pulldown protection prevents output voltage spikes during transient conditions.

Smoke and heat detectors
Thermostats
Motion detectors (PIR, uWave)
Cordless power tools
Appliance battery packs

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

Verify the specific manufacturing revision (new vs. legacy chip) as electrical characteristics such as quiescent current and dropout voltage differ significantly between versions. Confirm that the required output capacitance meets the minimum effective value specifications for stability. Ensure the enable pin logic levels align with the system control voltage.

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

Select this component for applications requiring a stable 3.8V rail from inputs up to 10V. Consider the new chip variant if lower quiescent current or improved line regulation is critical. Evaluate thermal dissipation capabilities based on the junction-to-ambient resistance of the SOT-23 package under expected load conditions.

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

This part belongs to the TPS763 series of low-dropout regulators designed for cost-sensitive designs where board space is limited. The family supports various fixed output voltages ranging from 1.6V to 5.0V. The DBV suffix indicates the 5-pin SOT-23 surface-mount package, which facilitates miniaturization in portable electronic devices.
