TC1301A-FHAVUATR

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

The TC1301A-FHAVUATR is a dual-output Low Dropout (LDO) regulator with an integrated microcontroller reset monitor, manufactured by Microchip Technology. It features two fixed output voltages: VOUT1 at 2.6V capable of 300mA and VOUT2 at 2.8V capable of 150mA. The device operates within an input voltage range of 2.7V to 6.0V. Key electrical characteristics include a typical dropout voltage of 104mV for VOUT1 and 150mV for VOUT2, with a supply current of 116µA when both outputs are active. It provides overcurrent and overtemperature protection.

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

Verify the specific suffix 'FHAV' against official datasheet tables to confirm the exact output voltage combination (2.6V/2.8V) and package type (DFN-8). Ensure compatibility with required ceramic output capacitance values for stability. Confirm RoHS compliance status through manufacturer documentation prior to integration.

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

Select this component when a compact solution combining dual LDOs and system reset monitoring is required. It is suitable for applications needing independent shutdown capability for one rail while maintaining continuous operation on the other. Consider thermal resistance requirements for the DFN-8 package in high-current scenarios.

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

This part belongs to the TC1301A/B family of dual LDO regulators from Microchip Technology. The 'TC1301A' designation indicates a variant where the RESET function monitors an external VDET pin, unlike the TC1301B which monitors VOUT1 internally. This family is designed for portable electronics requiring efficient power regulation.

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

Direct substitutes include other TC1301A variants with different voltage suffixes or the TC1301B series if internal reset monitoring is acceptable. Verify pinout compatibility and output current ratings before substitution.
