TC1073-2.5VCH713

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

The TC1073-2.5VCH713 is a fixed-output low dropout (LDO) voltage regulator manufactured by Microchip Technology, part of the TC1073 series. It provides a precise 2.5 V output with a maximum continuous current capability of 100 mA. The device operates within an input voltage range of 2.7 V to 6 V and features a typical dropout voltage of 85 mV at full load. Key electrical parameters include a quiescent supply current of 50 µA, line regulation of 0.05%, and load regulation of 0.5%. It offers high output voltage accuracy of ±0.5% and includes overcurrent and overtemperature protection. The component is housed in a space-saving SOT-23-6 surface-mount package.

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

Verify the specific suffix CH713 against official Microchip documentation to confirm the exact reel packaging quantity and tape-and-reel specifications. Ensure the ordering part number matches the required 2.5 V fixed output variant. Confirm RoHS compliance status through the manufacturer's latest product compliance reports before procurement.

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

Select this component when a stable 2.5 V rail is required from a single-cell lithium or alkaline battery source. The low dropout characteristic allows operation even as battery voltage depletes near the output level. The integrated error flag simplifies system monitoring without external comparators. Verify that the 100 mA load requirement does not exceed thermal limits in the chosen PCB layout environment.

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

This device belongs to the TC1073 family of CMOS LDO regulators designed as direct pin-compatible upgrades for older bipolar low-dropout regulators. The series includes variants with different output voltages and current ratings, such as the 50 mA TC1072. The TC1073 specifically targets applications requiring higher current drive while maintaining the low power consumption advantages of CMOS technology over legacy bipolar designs.

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

The TC1072 serves as a lower-current alternative within the same family. Direct pin-compatible replacements may exist among other Microchip LDOs; verify datasheet compatibility for specific voltage and current requirements.
