7 Detailed Description
7.1 Overview
The LMx85-2.5 and LM385B-2.5 devices maintain a nearly constant voltage between the cathode and anode of
2.5 V when the minimum cathode current up to the recommended maximum is provided. See Recommended
Operating Conditions for recommended minimum cathode current.
7.2 Functional Block Diagram
7.3 Feature Description
A band-gap voltage reference controls a high-gain amplifier and shunt pass element to maintain a nearly
constant voltage between the cathode and anode of 2.5 V. Regulation occurs after a minimum current is
provided to power the voltage divider and amplifier. Internal frequency compensation provides a stable loop for
all capacitive loads. Floating shunt design is useful for both positive and negative regulation applications.
7.4 Device Functional Modes
The LMx85-2.5 and LM385B-2.5 devices have a single functional mode. These devices can be used as 2.5-V
fixed voltage references. The reference voltage cannot be adjusted for these devices.
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).
