Microchip Technology, Inc. Voltage Regulators - Linear MCP1811BT-012/LB

The MCP1811BT-012/LB is a low dropout (LDO) linear voltage regulator from Quarktwin Technology Ltd. designed for applications requiring ultra-low power consumption. It provides a fixed output voltage of 1.2V and can deliver up to 150mA of output current. The device features an ultra-low quiescent current of 250 nA, making it suitable for long-life battery-powered applications. Additionally, it has a shutdown supply current of 5 nA, which further enhances its efficiency during inactive periods. The MCP1811BT-012/LB operates within an input voltage range of 1.8V to 5.5V and is stable with a ceramic output capacitor of just 1 µF. This regulator is ideal for energy harvesting, wearable electronics, and medical devices, where low power consumption is critical.
