MCP1790T-5002E/DB - PMIC - Voltage Regulators - Linear

The MCP1790T-5002E/DB is a voltage regulator from Microchip Technology’s family of low-noise, low-dropout linear regulators. It is designed to provide a regulated output voltage for a wide range of applications that demand low power consumption. This voltage regulator is especially suitable for portable handheld devices, such as cellular phones and PDAs, which require a low output current and low input and output voltage headroom.The MCP1790T-5002E/DB features a fixed output voltage of 5V, with a low dropout voltage of 0.45V at 500mA. It has an operating temperature range from -40C to +125C, and its quiescent current is typically 100µA. With its small size (2.4 x 1.4 mm), the MCP1790T-5002E/DB is well-suited for space-restricted designs, particularly in battery-powered applications.This voltage regulator has a wide input voltage operating range, from 2.7V to 16V. It also has low output ripple and low noise, which allows for better system performance. The MCP1790T-5002E/DB also features input current limiting and thermal shutdown protection, which make it suitable for a variety of applications.The MCP1790T-5002E/DB uses a linear regulating technique, which allows it to achieve low noise, low output ripple, and low power consumption. It consists of an error amplifier, a bandgap reference, a P-channel MOSFET, and a bias current amplifier, all of which are used to convert the input voltage to the regulated output voltage.The error amplifier compares the voltage of the feedback signal with the voltage output of the bandgap reference, and produces an error signal that is used to control the P-channel MOSFET. As the load changes, the P-channel MOSFET adjusts its conductance to maintain the output voltage constant. The bias current amplifier, which is used to generate the bias current for the error amplifier, is essential for proper operation of the device.The MCP1790T-5002E/DB is available in a variety of packages, including MSOP and DFN. The DFN package is the smallest and requires the least amount of space. It also has a maximum operating temperature of +125C and an offset voltage that can be externally adjusted.In summary, the MCP1790T-5002E/DB is suitable for many portable applications that require low power consumption and low input and output voltage headroom. Its wide input voltage range, low dropout voltage, and excellent noise suppression and output ripple make it an ideal solution for many applications. Additionally, its small size and excellent thermal and input current limiting protection make it ideal for space-restricted designs.
