The LT1009CD is a Voltage Reference from the PMIC (Power Management IC) range of products. It is a Voltage Reference and regulator device which provides a precise, temperature stable and low cost reference. The LT1009CD is ideal for battery-powered or low voltage systems or systems which require a low cost reference with low power consumption. It offers high accuracy across a wide temperature range and can also handle line input voltages of up to 36V, making it suitable for a wide range of applications.

The design of the LT1009CD is based on a bandgap topology and a precision resistor divider network. As a result the output voltage is constant over a wide range of temperature and line variations. The output voltage is set by two external resistors and the voltage is accurate over a wide temperature range. The output voltage can be adjusted from 2V up to 36V. The supplied accuracy is within 1mV for temperatures of 0 to 70°C and a maximum output current of 5mA.

The device functions as a voltage regulator, with a fixed output voltage. Its application fields include any situation where a precision voltage reference is required. Battery stack monitoring, dc/dc converter applications and temperature sensor reference voltage generator are all potential applications. The device is also suitable for low dropout linear regulator applications, or as the reference in portable instrumentation or laboratory grade power supplies.

The LT1009CD is designed to use a very low supply current, typically in the range of 10μA. This makes it ideal for systems which require a low power reference. The supply voltage can be as low as 1.3V or as high as 36V, so the device is suitable for low and high voltage systems. The CMOS process ensures low voltage offsets and wide bandwidths, making the device suitable for high performance applications. The device also features a low thermal stability of typically 0.1mV/°C over a temperature range of 0 to 70°C, making it suitable for a wide range of temperature sensitive applications.

In summary, the LT1009CD is a reliable, low cost and versatile voltage reference from the PMIC (Power Management IC) range of products. It is a Voltage Reference and Regulator device with a wide range of application fields including battery pack monitoring, dc/dc converters and temperature sensor reference voltage generator. It is capable of handling line input voltages up to 36V with a high accuracy across a wide temperature range, a low power consumption of less than 10μA, and a low thermal stability of 0.1mV/°C. It is suitable for a wide range of portable instruments, laboratory grade power supplies and other precision, low voltage systems.
