Microchip Technology, Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators MCP1811AT-010/OT

The MCP1811AT-010/OT is an ultra-low quiescent current linear voltage regulator designed for battery-powered applications. It features a typical quiescent current of 250 nA and a shutdown supply current of 10 nA, making it suitable for energy-efficient designs. This regulator can deliver an output current of up to 150 mA and operates within an input voltage range of 1.8V to 5.5V. The MCP1811AT-010/OT is available with a fixed output voltage of 1V and is stable with a ceramic output capacitor of just 1 µF, which helps reduce overall solution size and cost. It includes overcurrent protection and is suitable for applications such as smart cards, wearable electronics, and medical devices. The device is offered in a compact 5-lead SOT-23 package, making it a practical choice for space-constrained designs.
