TC2014-2.8VCTTR

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

The TC2014-2.8VCTTR is a fixed-output Low Dropout Regulator (LDO) manufactured by Microchip Technology, providing a regulated 2.8 V output with a maximum current of 50 mA. It operates within an input voltage range of 2.7 V to 6.0 V and features a typical dropout voltage of 45 mV at full load. The device incorporates a power-saving shutdown mode that reduces supply current to a maximum of 0.5 µA. It includes overcurrent and overtemperature protection mechanisms and maintains high accuracy with a typical output voltage tolerance of ±0.4%. The unit is housed in a space-saving 5-pin SOT-23 package.

• Linear post-regulators for switching mode power supplies

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

Verify the specific suffix CTTR corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the voltage code PD aligns with the necessary 2.8 V output specification for the target circuit design. Ensure compatibility with the SOT-23 footprint dimensions during PCB layout verification.

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

Select this component for applications prioritizing minimal standby power consumption due to its low shutdown current capability. Consider the 50 mA output limit when sizing for peak load requirements. Evaluate the need for the reference bypass pin if strict noise specifications are mandated for sensitive analog sections of the system.

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

This regulator belongs to the TC2014/2015/2185 family of CMOS LDOs designed as direct upgrades for older bipolar regulators like the LP2980. The series offers pin-compatible alternatives while significantly reducing total supply current compared to bipolar counterparts. The TC2014 specifically denotes the 50 mA variant within this lineup.

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

TC2015-2.8VCTTR provides identical electrical characteristics but supports a higher maximum output current of 100 mA. TC2185-2.8VCTTR offers the same form factor with a 150 mA maximum output current rating. Both serve as functional substitutes where increased load capacity is required without altering the board layout.
