1 / 18 page LM185-1.2QML www.ti.com SNVS384B – OCTOBER 2005 – REVISED JANUARY 2014 LM185-1.2QML Micropower Voltage Reference Diode Check for Samples: LM185-1.2QML 1 FEATURES DESCRIPTION The LM185-1.2 is a micropower 2-terminal band-gap 2 • Operating Current of 10 μA to 20mA voltage regulator diodes. Operating over a 10 μA to • 1 Ω Maximum Dynamic Impedance (Typical) 20mA current range, it features exceptionally low • Low Temperature Coefficient dynamic impedance and good temperature stability. On-chip trimming is used to provide tight voltage • Radiation Qualified Option tolerance. Since the LM185-1.2 band-gap reference – 100 krad uses only transistors and resistors, low noise and – Low Dose Rate Tested at 10 mrad/s good long term stability result. Careful design of the LM185-1.2 has made the device exceptionally tolerant of capacitive loading, making it easy to use in almost any reference application. The wide dynamic operating range allows its use with widely varying supplies with excellent regulation. The extremely low power drain of the LM185-1.2 makes it useful for micropower circuitry. This voltage reference can be used to make portable meters, regulators or general purpose analog circuitry with battery life approaching shelf life. Further, the wide operating current allows it to replace older references with a tighter tolerance part. Connection Diagrams Figure 1. LCCC Package Figure 2.
