This document describes the features and characteristics of the Precision Micropower, Low Dropout Voltage References REF19x series, including temperature coefficient, output current, supply current, and initial accuracy.
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.
| Temperature Coefficient (Max) | 5 ppm/°C |
|---|---|
| High Output Current | 30 mA |
| Low Supply Current (Max) | 45 μA |
| Initial Accuracy (Grade E) | ±2 mV |
| Operating Temperature Range | -40°C to +85°C |
The maximum supply current is less than 45 μA.
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.
All electrical grades are available in an 8-lead SOIC package.
