REF191 Datasheet Low Dropout Voltage References

Manufacturer: Analog Devices

Overview: Data Sheet Precision Micropower, Low Dropout Voltage References REF19x.

General Description

The REF19x series precision band gap voltage references use a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve a very low temperature coefficient and high initial accuracy.

The REF19x series is made up of micropower, low dropout voltage (LDV) devices, providing stable output voltage from supplies as low as 100 mV above the output voltage and consuming less than 45 μA of supply current.

In sleep mode, which is enabled by applying a low TTL or CMOS level to the SLEEP pin, the output is turned off and supply current is further reduced to less than 15 μA.

Key Features

  • Temperature coefficient: 5 ppm/°C maximum High output current: 30 mA Low supply current: 45 μA maximum Initial accuracy: ±2 mV maximum1 Sleep mode: 15 μA maximum Low dropout voltage Load regulation: 4 ppm/mA Line regulation: 4 ppm/V Short-circuit protection.
