Analog Devices REF19x Series Precision Micropower Low Dropout Voltage References Data Sheet
The REF19x series consists of precision band gap voltage references utilizing a patented temperature drift curvature correction circuit and laser-trimmed thin-film resistors. These devices are designed for micropower, low dropout (LDV) applications, capable of providing stable output voltages from supplies as low as 100 mV above the output voltage while consuming less than 45 μA of supply current.

Questions answered in these manuals
What is the maximum supply current for the REF19x series?
The maximum supply current is less than 45 μA.
From: Analog Devices REF19x Series Precision Micropower Low Dropout Voltage References Data Sheet
How does the sleep mode function work?
Sleep mode is enabled by applying a low TTL or CMOS level to the SLEEP pin, which turns off the output and reduces supply current.
