ref19x series precision micropower low dropout voltage references
The REF19x series includes the REF195 precision band‑gap voltage reference. It provides a stable 5 V output with an initial accuracy of ±2 mV, a temperature coefficient of 5 ppm/°C, and a low‑dropout voltage. The device operates from supplies as low as 100 mV above the output and consumes only 45 µA in normal mode, dropping to 15 µA in sleep mode.
Typical applications are portable instruments, ADCs/DACs, smart sensors, solar‑powered systems and loop‑current‑powered instruments. The REF195 is offered in 8‑lead SOIC, PDIP and TSSOP packages, with ordering options for tape and reel.
| Initial accuracy | +2 mV max |
|---|---|
| Temperature coefficient | 5 ppm/°C max |
| Low supply current (normal mode) | 45 µA |
| Supply current (sleep mode) | 15 µA |
| Maximum output current | 30 mA |
| Nominal output voltage (REF195) | 5.00 V |
The REF195 provides a nominal output voltage of 5.00 V.
The temperature coefficient is specified as 5 ppm/°C maximum.
In normal (no‑load) operation the device draws 45 µA.
