Microchip Technology MCP1825T-1202E/ET Low Dropout Voltage Regulator

The MCP1825T-1202E/ET is a high-performance, 500 mA Low Dropout (LDO) voltage regulator from Microchip Technology, designed to deliver a fixed output voltage of 1.2V with enhanced stability and efficiency. This component is part of the MCP1825 series, which is renowned for its low dropout voltage, making it ideal for battery-powered devices and applications that require efficient power management.

With an input voltage range of 2.1V to 6.0V, the MCP1825T-1202E/ET is versatile for various applications, from portable electronics to microcontroller power supplies. The low dropout voltage, typically just 210 mV at full load, allows for a reduced power loss and helps in maintaining regulation with lower input-to-output voltage differentials.

The LDO is encapsulated in a 5-Terminal SOT-223 package, which is both space-saving and offers a thermal advantage for better heat dissipation. The device also features a high PSRR (Power Supply Rejection Ratio) of 70 dB at 1 kHz, which is critical for applications that demand a stable voltage supply even with a noisy or fluctuating input.

Furthermore, the MCP1825T-1202E/ET incorporates several protective features that ensure the longevity and reliability of both the regulator and the system it powers. These include short-circuit protection, overcurrent protection, and overtemperature protection. Additionally, the device supports a stable output with only a 1.0 µF ceramic output capacitor, which is beneficial for space-constrained designs.
