XC6701AA12MR-G

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

The XC6701AA12MR-G is a positive fixed-output low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor. It provides a stable 12V output with a maximum continuous current of 150mA. The device operates from an input voltage range up to 28V and features a typical dropout voltage of 0.85V at 100mA load. Key electrical specifications include a quiescent current of 115µA, power supply rejection ratio (PSRR) of 50dB at 1kHz, and line regulation of 0.15%/V. It is housed in a compact SOT-25-5 surface-mount package.

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

Verify the specific suffix 'MR' corresponds to the SOT-25-5 package configuration required for your PCB layout. Confirm that the 12V fixed output aligns with system design requirements, as this parameter is non-adjustable. Ensure input voltage does not exceed the 28V absolute maximum rating under all operating conditions. Check datasheet for thermal derating curves if operating near the upper temperature limit.

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

Select this component when a fixed 12V rail is needed from higher voltage sources up to 28V. It is suitable for applications prioritizing simplicity and low noise over adjustable output flexibility. Consider the 150mA current limit for load requirements. The SOT-25-5 package is ideal for space-constrained designs compared to larger through-hole alternatives.

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

This part belongs to the XC6701 series of high-speed voltage regulators. The series utilizes CMOS technology to achieve low quiescent current and high PSRR. The 'AA' designation typically indicates the specific output voltage code within the product family, distinguishing it from other fixed voltage variants like 5V or 3.3V versions.

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

Direct substitutes may include other XC6701 series variants with different output voltages if the voltage requirement changes, such as XC6701AA05MR-G for 5V output. Cross-brand replacements require matching input voltage, output current, package type, and protection features.
