TC1301B-AIAVMF

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

The TC1301B-AIAVMF is a dual-output Low Dropout (LDO) regulator with an integrated microcontroller reset monitor, manufactured by Microchip Technology. It features two independent LDO outputs: VOUT1 provides up to 300 mA and VOUT2 provides up to 150 mA. The device operates within an input voltage range of 2.7 V to 6.0 V. Both outputs are stable with a minimum of 1 µF ceramic capacitors. The TC1301B variant includes separate SHDN1 and SHDN2 pins for independent shutdown control of each output.

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

• Integrates two low dropout regulators and a microcontroller reset function in a single package
• Provides independent shutdown capability for both VOUT1 and VOUT2 via dedicated control pins
• Includes a reference bypass pin to reduce output noise and improve power supply rejection ratio
• Features overcurrent limit and overtemperature protection for robust load fault handling

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

• Cellular/GSM/PHS phones
• Battery-operated systems
• Hand-held medical instruments
• Portable computers/PDAs
• Linear post-regulators for SMPS

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

Verify the specific suffix 'AIAVMF' against the manufacturer's official datasheet or ordering guide to confirm exact output voltage combinations and package type. Ensure compatibility with required thermal management solutions given the operating junction temperature range. Confirm RoHS compliance status through current documentation before finalizing procurement specifications.

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

Select this component when independent shutdown control for both LDO outputs is required, distinguishing it from the TC1301A which lacks SHDN1. Verify that the fixed output voltage options match the system requirements. Consider the internal connection of the RESET detector to VOUT1 for applications where monitoring the primary rail is sufficient.

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

This part belongs to the TC1301A/B family of dual LDO regulators designed for portable electronics. The TC1301B specifically differentiates itself by offering independent shutdown inputs for both outputs, whereas the TC1301A only controls VOUT2. Both variants share similar electrical characteristics regarding dropout voltage and quiescent current consumption.

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

TC1301A-BIAVMF offers identical electrical performance but lacks the SHDN1 pin for VOUT1 shutdown control. TC1301B-ADAVMF provides alternative fixed output voltage combinations while maintaining the same package and functional interface.
