TC1269-5.0VUATR

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

The TC1269-5.0VUATR is a fixed-output, high-accuracy CMOS low dropout regulator manufactured by Microchip Technology. It provides a regulated 5.0 V output with a maximum current of 300 mA. The device operates within an input voltage range of 2.7 V to 6.0 V and features a typical supply current of 50 µA at full load. Dropout voltage is specified as 80 mV at 100 mA and 240 mV at 300 mA. Output voltage accuracy is typically ±0.5%. The unit includes power-saving shutdown mode reducing current to 0.05 µA, over-current protection, and thermal shutdown. It 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 MSOP-8 package and standard tube packaging when reviewing distributor listings. Confirm that the 'TR' suffix variant indicates tape-and-reel packaging if reel quantities are required. Ensure the component meets RoHS compliance standards applicable to your region before finalizing procurement orders.

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

Select this component for applications requiring precise 5.0 V regulation with minimal quiescent current draw. The inclusion of a shutdown pin allows for system-level power management control. Verify that the external capacitor selection meets the ESR requirements for stability. Consider the thermal resistance characteristics of the MSOP package for high-load environments.

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

This part belongs to the TC1269 family of 300mA CMOS LDOs designed as upgrades for older bipolar regulators. The family offers various fixed output voltages including 2.5V, 2.8V, 3.0V, 3.3V, and 5.0V. All variants share similar electrical characteristics and package options, differing primarily in their internal reference voltage settings.
