PMIC voltage references are widely used in various applications to provide precision voltage references across a wide range of conditions. The REF192ES is a low temperature coefficient voltage reference designed specifically for operation in high temperature environments. It was designed to provide high performance over extended operation in harsh environmental conditions.

The REF192ES is a zero-drift, low temperature coefficient voltage reference that offers superior accuracy, stability, and temperature performance. It operates over a temperature range of -55°C to +125°C, and has a wide output voltage range of 1.24V to 9.76V. This device is well suited for use in automotive applications, industrial process control, and medical systems. The REF192ES is offered in a 2mm x 2mm SOT-23-6 package, making it suitable for applications where space and power are limited.

The REF192ES is a comprehensive voltage reference with many features for reliable operation. The device includes on-chip bandgap circuitry and temperature compensation to ensure that the output voltage remains stable over the full range of operating temperature and supply conditions. The device also includes a shutdown mode with extremely low current draw, and hysteresis to guard against latchup due to static electricity.

The REF192ES employs a dual tracking technique to generate a very precise output voltage. This technique uses two transistors, one to control the voltage output, and the other to provide temperature compensation and supply regulation. The dual transistors are connected in series, and the junction between the two transistors provides the output voltage. When temperatures or supply conditions fluctuate, the voltage output is adjusted by changing the current flowing through the output transistor.

This technique is superior to other methods of providing a voltage reference because it is self-regulated and does not need external components to stabilize the output. The REF192ES also has an active-low shutdown feature, which reduces the current consumption of the device to 1µA. This allows for power savings in battery powered applications.

The REF192ES is a high-precision voltage reference device that can be used in many different applications. It is especially suitable for use in automotive, medical and industrial systems that require precise voltages over extended environmental temperature range. The device is offered in a SOT-23-6 package, which occupies minimal board space, and supports a wide range of input and output conditions. The integrated temperature compensation and hysteresis protection make this device ideal for harsh conditions and reliable operation.
