TC1300R-3.3VUATR

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

The TC1300R-3.3VUATR is a fixed-output low dropout regulator with an integrated microcontroller reset monitor, housed in an 8-pin MSOP package. It provides a 3.3 V output at up to 300 mA with ±0.5% accuracy. The device operates from a 2.7 V to 6.0 V input supply and features a typical quiescent current of 80 µA. It includes a separate detected voltage input (VDET) for the reset function, which asserts an active-low signal when VDET falls below a 2.63 V threshold. The RESET output remains valid for a minimum of 140 msec after the threshold is exceeded.

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

• Combines a 300 mA LDO with a microcontroller reset monitor in a single space-saving package
• Features independent shutdown control that reduces supply current to 30 µA while maintaining a valid RESET output
• Includes an optional bypass input for improved noise performance and power supply rejection ratio
• Provides over-current and over-temperature protection with internal feed-forward compensation

• Cellular / GSM / PHS phones

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

Verify the specific suffix 'TR' indicates tape and reel packaging rather than tube. Confirm the 'R' designation corresponds to the 2.63 V reset threshold required by your system logic. Ensure the 8-lead MSOP footprint matches your PCB layout guidelines. Check for RoHS compliance status on the latest datasheet revision before finalizing procurement.

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

Select this component when a combined power regulation and system reset solution is needed to minimize board space. It is suitable for applications requiring fast wake-up times from shutdown states. Consider the thermal resistance of the MSOP package if high ambient temperatures or significant power dissipation are expected in the design environment.

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

This part belongs to the TC1300 family of micropower CMOS LDOs manufactured by Microchip Technology. The family integrates standard linear regulation capabilities with dedicated reset monitoring functions. Variants within the series differ primarily in their fixed output voltage settings and the specific voltage thresholds used for the reset detection circuitry.
