LM385BZ Micropower Voltage Reference Diode

The LM385 is micropower 3-terminal adjustable band-gap voltage reference diodes. Operating from1.24 to 5.3V and over a 10µA to 20mA current range, it features exceptionally low dynamic impedance and good temperature stability. On-chip trimming is used to provide tight voltage tolerance. Since the LM185 band-gap reference uses only transistors and resistors, low noise and good long-term stability result. The careful design of the LM185 has made the device 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 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
