TPS78512BQWDRBRQ1

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

The TPS78512BQWDRBRQ1 is an automotive-grade low-dropout linear voltage regulator from the Texas Instruments TPS785-Q1 family. It provides a fixed 1.2 V output with a maximum continuous current of 1 A. The device operates within an input voltage range of 1.7 V to 6.0 V and features high accuracy, typically 0.5% at 25°C. It utilizes a wettable flank VSON (8) package measuring 3 mm by 3 mm. Key electrical characteristics include a typical quiescent current of 25 µA, a dropout voltage of 725 mV maximum at 1 A load, and a power supply rejection ratio of 60 dB at 1 kHz.

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

High-accuracy regulation with internal bandgap reference ensuring stable output voltages across temperature variations.
Integrated enable pin allows for precise power sequencing control and system-level shutdown management.
Internal soft-start circuitry limits inrush current during startup, reducing stress on input capacitors.
Active output discharge rapidly removes stored charge from the output node when the device is disabled.

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

Verify the specific suffix 'BR' indicates the B-version DRB package with wettable flanks, which supports automated optical inspection. Confirm the component meets AEC-Q100 Grade 1 requirements for the intended ambient temperature range. Ensure the ordering part number matches the fixed 1.2 V output variant to avoid confusion with adjustable versions or different package types like TO-252.

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

Select this component when a fixed 1.2 V rail is required for sensitive analog loads in automotive environments. The high PSRR makes it suitable for post-regulation of DC/DC converters. Consider the thermal resistance of the VSON package if operating near maximum junction temperatures. Verify that the input voltage remains above the minimum dropout threshold under all load conditions.

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

This device belongs to the TPS785-Q1 series of ultra-low-dropout regulators designed specifically for automotive electronics. The series offers flexibility through both adjustable and fixed output options, catering to various voltage rail requirements.
