TPS767D318PWPR

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

The TPS767D318PWPR is a dual-output low-dropout (LDO) voltage regulator from Texas Instruments, housed in a 28-pin PowerPAD HTSSOP package. It provides fixed outputs of 3.3V and 1.8V, each capable of delivering up to 1A of output current. The device features ultra-low quiescent current of typically 85µA and supports fast transient response with 10µF low ESR output capacitors. Integrated power-on reset signals provide independent monitoring for both regulators.

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

• Dual-output architecture providing simultaneous 3.3V and 1.8V rails
• Ultra-low quiescent current consumption for battery efficiency
• Integrated open-drain power-on reset signals for system supervision
• Thermal shutdown protection for each individual regulator channel

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

• DSP applications requiring split-supply voltages
• Mixed-signal systems needing separate core and I/O power
• Battery-powered portable devices
• Microprocessor and microcomputer system power management

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

Verify the specific suffix 'PWPR' corresponds to the 28-pin HTSSOP PowerPAD package and tape-and-reel shipping configuration. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the input voltage range accommodates your system's supply variations while maintaining the specified dropout performance under maximum load conditions.

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

Select this component when a compact solution is needed for generating two distinct logic levels from a single source. The fixed 3.3V/1.8V combination suits standard digital interfaces. Consider the thermal performance of the PowerPAD package if high ambient temperatures or continuous full-load operation are expected within the -40°C to +125°C operating range.

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

This part belongs to the TPS767D3xx family of dual-output LDOs designed primarily for DSP environments. The series integrates stability with minimal external components and offers low dropout characteristics due to PMOS pass elements. It serves as a power management solution for mixed-voltage digital systems requiring efficient regulation and system supervision.

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

The TPS767D301PWPR is a functional substitute offering 3.3V and adjustable outputs instead of fixed 1.8V. The TPS767D325PWPR provides 3.3V and 2.5V outputs. Verify pin compatibility and output voltage requirements before substituting these variants within the same family.
