REF191-EP Datasheet Low Dropout Voltage Reference

Manufacturer: Analog Devices

Overview: Enhanced Product.

General Description

The REF191-EP precision band gap voltage reference uses a proprietary 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 REF191-EP is a micropower, low dropout voltage device, providing stable output voltage from supplies with low headroom and consuming less than 50 µA of supply current.

In sleep mode, which is enabled by applying a low transistor to transistor logic (TTL) or complementary metal-oxide semiconductor (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: 50 µA maximum Initial accuracy: 2.050 V maximum Sleep mode: 15 µA maximum Low dropout voltage Load regulation: 4 ppm/mA typical at TA = 25°C Line regulation: 2 ppm/V typical at TA = 25°C Short-circuit protection.
