MCP1812BT-012/LT

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

The MCP1812BT-012/LT 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 300 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. In shutdown mode, it achieves a typical supply current of 5 nA. The component is housed in a 3-Lead SC70 package and supports stable operation with ceramic output capacitors.

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

Verify that the specific suffix 'LT' corresponds to the 3-Lead SC70 package configuration as documented in the official datasheet. Confirm that the 'B' designation indicates the absence of an internal output discharge switch, which differs from the 'A' variant. Ensure compatibility with the required 2.2 µF minimum ceramic output capacitance for system stability.

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

Select this component when designing circuits requiring high current delivery alongside minimal power drain during sleep states. The 300 mA rating distinguishes it from the 150 mA MCP1811X series. Consider the lack of active output discharge if rapid voltage decay is not required. Verify thermal performance within the specified -40°C to +85°C operating junction temperature range.

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

This part belongs to the MCP1811A/11B/12A/12B family of ultra-low quiescent current LDO regulators. The family includes variants with 150 mA and 300 mA output capabilities. The 'B' suffix denotes devices without the output discharge feature found in 'A' series parts. These regulators are engineered for applications demanding high efficiency and long operational lifespans from limited energy sources.
