8 Detailed Description
8.1 Overview
The LM285-1.2, LM385-1.2, and LM385-1.2 devices are micropower, two-terminal, band-gap voltage references
which operate over a 10-
μA to 20-mA current range. On-chip trimming provides tight voltage tolerance. The
band-gap reference for these devices has low noise and long-term stability.
The design makes these devices exceptionally tolerant of capacitive loading and, thus, easier to use in most
reference applications. The wide dynamic operating temperature range accommodates varying current supplies,
with excellent regulation.
The extremely low power drain of this series makes them useful for micropower circuitry. These voltage
references can be used to make portable meters, regulators, or general-purpose analog circuitry, with battery life
approaching shelf life.
8.2 Functional Block Diagram
A.
Component values shown are nominal.
8.3 Feature Description
A band gap voltage reference controls high gain amplifier and shunt pass element to maintain a nearly constant
voltage between cathode and anode. Regulation occurs after a minimum current is provided to power the voltage
divider and amplifier. Internal frequency compensation provides a stable loop for all capacitor loads. Floating
shunt design is useful for both positive and negative regulation applications.
8.4 Device Functional Modes
LM285-1.2, LM385-1.2, and LM385-1.2 devices will operate in one mode, which is as a fixed voltage reference
that cannot be adjusted.
In order for a proper Reverse Voltage to be developed, current must be sourced into the cathode of LM285. The
minimum current needed for proper regulation is denoted in Electrical Characteristics as IZ,min.
