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

Verify the specific suffix 'VAO' against official Microchip documentation to confirm automotive qualification status, as datasheet text does not explicitly define this suffix's functional impact. Confirm package marking details and reel specifications match procurement requirements. Ensure environmental compliance data aligns with project constraints.

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

Select this component when a 150 mA adjustable LDO with shutdown control is required. It serves as a direct replacement for older bipolar regulators in space-constrained designs. Consider the SOT-23-5 package dimensions and thermal resistance characteristics during PCB layout planning to ensure adequate heat dissipation under maximum load conditions.

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

This part belongs to the TC1070/TC1071/TC1187 family of adjustable CMOS LDOs. The TC1187 variant specifically offers the highest current capability at 150 mA among the series. These devices are designed to supersede older bipolar voltage regulators while maintaining pin compatibility and offering significantly lower supply currents.

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

The TC1070 (50 mA) and TC1071 (100 mA) are pin-compatible variants within the same family. For fixed voltage applications, consider the TC1014 or TC1015 series. Higher current requirements may necessitate the TC1174 (300 mA) device.
