MICROCHIP MCP1826T LDO Voltage Regulator, Adjustable 800mV to 5V, 1A Output, Sō

The MICROCHIP MCP1826T-ADJE/DC is a high-performance, ceramic output capacitor stable Low Dropout (LDO) voltage regulator, designed to deliver a robust 1A output current. It features an adjustable output voltage range from 800mV to 5.0V, making it an exceptional choice for modern, power-sensitive applications requiring sub-1.8V rails. This regulator combines high-current capability with very low dropout voltage, ensuring efficient operation even when the input voltage is barely above the desired output level.

A key advantage of the MCP1826 is its stability with just a 1µF ceramic output capacitor. This inherent design feature not only reduces overall solution size but also contributes to lower output noise, which is critical for sensitive analogue and digital circuits. The device boasts a typical low quiescent current of 120µA and an ultra-low shutdown current of less than 0.1µA, maximising power efficiency in battery-powered systems.

Primary Features & Benefits:

• High Current, Low Voltage: Provides 1000mA output current at voltages as low as 0.8V, ideal for new generation processors and FPGAs.
• Low Dropout Voltage: Features a typical dropout of just 250mV at full load, minimising power loss and heat generation.
• Ceramic Capacitor Stable: Requires only a small 1µF ceramic output cap for stability, reducing board space and Bill of Materials (BOM) cost.
• Excellent Efficiency: Very low ground current in both active and shutdown modes preserves battery life.
• Robust Design: Offered in a compact SOT-223-5 surface-mount package, suitable for automated assembly.
