MCP1811AT-012/HCA

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

The MCP1811AT-012/HCA is a fixed-output Low Dropout (LDO) linear regulator from the MCP1811A/11B/12A/12B family, manufactured by Microchip Technology. It provides a nominal output voltage of 1.2V with a maximum continuous output current capability of 150 mA. The device operates within an input voltage range of 1.8V to 5.5V and maintains an ultra-low quiescent current of 250 nA during normal operation. It features overcurrent protection and is designed for stability with ceramic output capacitors.

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

Ultra-low quiescent current consumption of 250 nA typical during active operation
Integrated output discharge circuitry that activates when the shutdown pin is pulled low
Overcurrent protection mechanism to prevent damage during short-circuit events
Stable performance with small-value ceramic output capacitors

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

Energy harvesting systems
Long-life battery-powered applications
Smart cards
Wearable electronics such as smart watches and headsets
Medical devices including hearing aids

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

Verify the specific suffix 'HCA' against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required 1.2V fixed output and 150mA current rating for your design. Confirm availability status as distribution channels may vary.

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

Select this component when a fixed 1.2V rail is required with minimal standby power drain. The integrated output discharge feature distinguishes it from the 'B' variant, making it suitable for designs requiring rapid output voltage removal. Ensure the application load does not exceed the 150mA limit.

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

This part belongs to the MCP1811X series, which offers 150mA output current capability. It is distinct from the MCP1812X series, which provides 300mA. The 'A' designation indicates the presence of the output discharge function, whereas the 'B' variant lacks this feature. The family supports various standard fixed output voltages between 1V and 4V.
