MICROCHIP MCP1824T-ADJE/OT LDO Voltage Regulator, 300mA, SOT-23-5

The MICROCHIP MCP1824T-ADJE/OT is a low voltage, low quiescent current LDO linear regulator, designed to deliver high current and low output voltages for advanced electronic applications. With a 300mA output current capability and support for output voltages as low as 800mV, this regulator is an excellent choice for new sub-1.8V LDO designs that demand high performance.

This adjustable regulator operates over an input voltage range of 2.1V to 6V, with a typical dropout voltage of just 200mV, ensuring efficient power conversion. It is stable with only 1µF of ceramic output capacitance, which reduces output noise and minimizes the overall solution size and cost. The CMOS construction keeps quiescent current typically below 120µA, making it ideal for portable computing devices that require high output current with minimal power loss.

The MCP1824 family includes a shutdown (SHDN/) pin, reducing quiescent current to less than 0.1µA when disabled. It also features fast response to load transients, a fixed delay on the power good output, short-circuit current limiting, and overtemperature protection. The power good (PWRGD) output provides system status monitoring, and the ±0.4% output voltage tolerance ensures precise regulation.

Housed in a compact SOT-23-5 surface-mount package, the regulator operates over a wide temperature range from -40°C to +125°C, making it suitable for demanding environments. Its features make it a versatile solution for communications, networking, computer peripherals, and portable devices.
