TC1107-2.5VUA

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

The TC1107-2.5VUA is a fixed-output, high-accuracy CMOS low dropout regulator manufactured by Microchip Technology. It provides a nominal output voltage of 2.5V with a maximum output current of 300mA. The device operates within an input voltage range of 2.7V to 6.0V and features extremely low supply current, typically 50µA at full load. It incorporates power-saving shutdown mode, reducing supply current to 0.05µA typical when disabled. The component includes overcurrent and overtemperature protection and is housed in an 8-pin MSOP package.

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

Verify the specific suffix 'UA' corresponds to the 8-pin MSOP package configuration. Confirm the output voltage setting matches the required 2.5V specification. Ensure the application environment remains within the specified -40°C to +125°C junction temperature range. Check datasheet requirements for minimum output capacitance and ESR values to maintain stability.

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

Select this component for applications requiring a fixed 2.5V rail with moderate current demands up to 300mA. Consider the MSOP package for space-constrained designs. Evaluate the need for the shutdown pin; if unused, it must be tied to the input supply. Verify that the input voltage source can support the minimum operating voltage of 2.7V while accounting for dropout voltage under load.

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

The TC1107 series serves as a CMOS upgrade to older bipolar low dropout regulators, offering significantly lower supply currents. The TC1107-2.5VUA specifically denotes the 2.5V fixed output variant packaged in an 8-pin MSOP format. This family is designed for precision regulation in portable and battery-powered electronics where efficiency and size are critical constraints.

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

Other variants within the TC1107 family offer different fixed output voltages such as 2.8V, 3.0V, 3.3V, and 5.0V. The TC1107-xxVOA variant provides the same electrical characteristics but utilizes an 8-pin SOIC package instead of MSOP. Custom output voltages may be available upon request from the manufacturer.
