MCP1754T-3302E/OT: A 150mA, Low-Quiescent Current LDO Voltage Regulator from Microchip

In the world of modern electronics, efficient power management is a cornerstone of design, especially for battery-powered and space-constrained applications. The MCP1754T-3302E/OT from Microchip Technology stands out as a highly optimized Low-Dropout (LDO) voltage regulator engineered to meet these exact demands. This component delivers a stable 3.3V output from an input voltage range of 2.7V to 5.5V, making it an ideal choice for a wide array of portable devices.

A defining characteristic of this LDO is its remarkably low quiescent current, which typically measures just 900 nA. This ultra-low self-consumption is a critical advantage for applications where extending battery life is paramount. By minimizing the current drawn by the regulator itself when under light or no load, it ensures that more energy is dedicated to the core functionality of the end product, thereby significantly enhancing operational longevity.

Despite its minimal power footprint, the MCP1754T-3302E/OT does not compromise on performance. It is capable of supplying a continuous output current of 150mA, sufficient to power microcontrollers, sensors, and other peripheral components commonly found in IoT nodes, wearables, and medical devices. The device also features a low dropout voltage, typically 178 mV at 150 mA load, allowing it to continue regulating effectively even as the input voltage approaches very close to the output level, which is crucial for maximizing battery usage.

Housed in a space-saving SOT-23-5 package, this regulator is designed for compact PCB layouts. It incorporates key protection features such as current limit and thermal shutdown, safeguarding both the regulator and the downstream circuitry from fault conditions. Furthermore, it offers excellent line and load regulation, ensuring a stable and clean output voltage.

ICGOODFIND: The Microchip MCP1754T-3302E/OT is an exceptional LDO voltage regulator that masterfully balances ultra-low power consumption with robust output capability. Its combination of 150mA output, 900 nA quiescent current, and a small form factor makes it a superior choice for designers focused on efficiency and miniaturization in battery-dependent applications.
