Microchip Technology, Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators MCP1812AT-030/LB

The MCP1812AT-030/LB is a low dropout (LDO) linear voltage regulator designed for applications requiring a stable output voltage of 3.0V with a maximum output current of 300 mA. It operates within an input voltage range of 1.8V to 5.5V, making it suitable for various battery-powered devices. The device features an ultra-low quiescent current of 250 nA, which is beneficial for energy-efficient applications, particularly in long-life battery-powered devices. Additionally, it has a shutdown supply current of 5 nA, further enhancing its low power consumption profile. This regulator is stable with ceramic output capacitors, requiring only 2.2 µF for stability, which helps reduce overall solution size and cost. The MCP1812AT-030/LB includes overcurrent protection and is available in a compact SC70-3 package, making it ideal for space-constrained applications such as wearable electronics and medical devices. Its combination of low power consumption, high output current capability, and small footprint makes it a suitable choice for engineers looking for efficient voltage regulation solutions in their designs.
