TC1301A-AAAVUA

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

The TC1301A-AAAVUA is a dual-output Low Dropout (LDO) regulator with an integrated microcontroller reset function, manufactured by Microchip Technology. It features two fixed output voltages: VOUT1 at 3.3V capable of 300 mA and VOUT2 at 3.3V capable of 150 mA. The device operates within an input voltage range of 2.7 V to 6 V. Key electrical parameters include a typical dropout voltage of 104 mV at 300 mA for VOUT1 and 150 mV at 150 mA for VOUT2. Quiescent current consumption is 58 µA per regulator. The unit provides overcurrent and overtemperature protection, utilizes an 8-pin MSOP package, and supports operation from -40°C to +125°C.

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

Verify the specific suffix 'AAAVUA' corresponds to the required 3.3V fixed output configuration and MSOP-8 packaging. Confirm RoHS compliance status through official Microchip documentation prior to ordering. Ensure design requirements align with the specified 2.7 V to 6 V input range and thermal characteristics for the target operating environment.

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

Select this component when a dual rail power solution with system reset monitoring is required in a compact footprint. The TC1301A variant is appropriate if VOUT1 requires continuous operation without shutdown control, while VOUT2 needs independent enablement. Consider the TC1301B series if independent shutdown control for both outputs is necessary.

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

The TC1301A belongs to the TC1301A/B family of micropower CMOS LDOs designed for battery-powered applications. This series combines linear regulation with voltage supervision to simplify board layout and reduce component count. The AA suffix denotes the specific fixed output voltage combination, while VUA indicates the MSOP-8 surface mount package type.
