Linear voltage regulators are commonly used to convert high input voltages into low output voltage and to stabilize the output voltage to meet the fluctuation of the input voltage. The MCP1827-1802E/ET is a series of low dropout linear voltage regulators that offer high performance and provide a cost effective solution for any voltage regulator application requiring an output voltage of 1.25V to 5.0V.

The devices in the MCP1827-1802E/ET series are designed for applications requiring low quiescent current, low noise and minimal temperature drift. With a maximum operating temperature range of -40°C to +125°C, the MCP1827-1802E/ET devices are suitable for a wide range of applications including automotive, industrial and consumer products. The devices are available in fixed output voltage options ranging from 1.25V to 5.0V.

The MCP1827-1802E/ET series of voltage regulators feature a wide input voltage range from 3.3V to 24V and an output voltage accuracy of ±2.5%. The quiescent current for the device is limited to a maximum of 12µA which is ideal for battery powered applications. Other features include a low dropout voltage of 240mV at 1A and over-temperature and reverse polarity protection.

The working principle of the MCP1827-1802E/ET series is based on linear voltage regulation, which is based on a simple resistive divider. The divider is composed of two resistors – one connected between input voltage and ground and the other connected between output voltage and ground. The input voltage and output voltage are related by the ratio of the two resistors and this determines the output voltage. The series includes an on-board adjustment pin which is used to set the output voltage of the device.
