LT6658BHMSE-5#PBF is a 3-terminal adjustable voltage reference device within the PMIC – Voltage Reference family. It uses a combination of external reference resistors (REF1 and REF2) and a NPN bipolar transistor (Q1) to maintain a precise DC output voltage that is proportional to its current. The voltage references are available in the SOT-23 package, making them ideal for applications that require low-power and small form factor.

The LT6658BHMSE-5#PBF can drive up to 20mA of output current with a guaranteed 10mV initial accuracy and 0.5% accuracy over temperature range. It features a wide input voltage range (1.8V to 18V) and no adjustable reference voltage is needed. The voltage references have been optimized for applications including power supplies, battery-powered systems, A/D and D/A converters and more.

The LT6658BHMSE-5#PBF features a 0.8V to 5.5V output voltage range and wide 0.8V to 16V differential input voltage range. It can also provide up to 0.8V of guaranteed headroom, which is advantageous for use in high-side applications and applications with multiple supply voltages. In addition, the LT6658BHMSE-5#PBF has low power consumption, making it ideal for battery-powered systems. It can operate from a single supply and provide an output voltage that is higher than, lower than, or equal to the supply voltage.

The LT6658BHMSE-5#PBF utilizes a bipolar transistor inside the package and an external reference voltage and resistors to establish the output voltage. The base current is regulated to a constant level with the external resistors forming a voltage divider. The voltage across the voltage divider is filtered by the internal transistor and output at the voltage reference pin (VC).

The LT6658BHMSE-5#PBF provides ultra-stable output performance over temperature. Its high stability and accuracy ensure a reliable, low-power and low-cost voltage reference for power supplies, battery-powered systems and A/D and D/A converters. A low input current of 0.8µA at 18V further reduces power consumption, allowing the device to operate over a wider range of operating conditions.

In addition, the LT6658BHMSE-5#PBF features a low-noise quiescent output voltage of 100µV, making it suitable for high-speed applications. It can also be used as a voltage reference in positive, negative and zero-transition circuits and its wide input voltage range makes it ideal for applications with multiple supply voltages.

The LT6658BHMSE-5#PBF is a great choice for a variety of applications including temperature measurement and control, A/D and D/A converters, communications equipment, motor controllers, automotive and industrial systems, power supplies, and more. Its versatile performance and wide temperature range make it an ideal choice for low-power, low-cost and reliable voltage reference applications.
