MCP1700T-3002E/TT: A 3.0V, 200mA Low-Quiescent Current LDO Voltage Regulator from Microchip

In the world of low-dropout (LDO) voltage regulators, efficiency and stability are paramount, especially for battery-powered applications. The MCP1700T-3002E/TT from Microchip Technology stands out as a premier solution, offering a robust combination of ultra-low quiescent current and reliable performance in a compact package. This device is specifically designed to deliver a fixed 3.0V output with a maximum current of 200mA, making it an ideal choice for a wide range of portable and power-sensitive electronics.

One of the most significant features of the MCP1700T-3002E/TT is its remarkably low quiescent current of just 1.6 µA (typical). This characteristic is crucial for extending battery life in applications that spend long periods in standby or sleep modes, such as IoT sensors, wearable devices, and medical monitoring equipment. Unlike traditional LDOs that can draw milliamps of ground current even under light loads, the MCP1700T ensures that minimal power is wasted, thereby maximizing operational uptime.

Despite its low power consumption, this regulator does not compromise on performance. It boasts a low dropout voltage of 178 mV (typical) at 80 mA load, which allows it to continue regulating the output voltage even when the input voltage is very close to the output level. This is particularly advantageous when using batteries, as it permits the system to utilize almost the entire battery discharge cycle without a drop in performance. Furthermore, the device incorporates overcurrent protection and thermal shutdown features, safeguarding both the regulator and the downstream circuitry from potential damage due to fault conditions.

The MCP1700T-3002E/TT is offered in a space-saving SOT-23-3 package, which is highly desirable for modern, miniaturized PCB designs. Its design ensures stable operation with a low-ESR ceramic output capacitor, which helps reduce the overall component count and board space. With an input voltage range from 2.7V to 13.2V, it offers flexibility for various power sources, including multi-cell battery packs.

ICGOODFIND: The MCP1700T-3002E/TT is an exceptional LDO regulator that masterfully balances ultra-low power consumption with reliable voltage regulation. Its standout features make it an indispensable component for designers focused on enhancing the battery life and efficiency of their portable electronic products.
