On-chip trimming provides tight voltage tolerance. The band-gap reference for these devices has low noise and long-term stability. 1 • Operating Current Range 20 μA to 20 mA 1.5% and 3% Initial Voltage Tolerance Reference Impedance – LM385 1 Ω Maximum at 25°C – All Devices 1.5 Ω Maximum Over Full Temperature Range Very Low Power Consumption 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. 2 Applications • • • • • Portable Meter References Portable Test Instruments Battery-Operated Systems Current-Loop Instrumentation Panel Meters The extremely low power drain of this series makes these devices 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. The wide operating current range of these voltage references allows them to replace older references with tighter-tolerance parts.

See Recommended Operating Conditions for recommended minimum cathode current. 7.2 Functional Block Diagram CATHODE Q13 600 kΩ 7.5 kΩ Q12 Q4 Q7 200 kΩ Q11 Q3 50 kΩ Q10 Q1 20 pF 300 kΩ 20 pF 500 kΩ Q9 Q2 Q5 Q6 500 Ω 100 kΩ Q8 Q14 500 kΩ 60 kΩ ANODE 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. 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). 8 Submit Documentation Feedback Copyright © 1989–2018, Texas Instruments Incorporated Product Folder Links: LM285-2.5 LM385-2.5 LM385B-2.5 LM285-2.5, LM385-2.5, LM385B-2.5 www.ti.com SLVS023L – JANUARY 1989 – REVISED FEBRUARY 2018 8 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The LMx85-2.5 and LM385B-2.5 devices create a voltage reference for use in a variety of applications including amplifiers, power supplies, and current-sensing circuits. 8.2 Typical Application Figure 8 shows how to use these devices to establish a 2.5-V source from a 9-V battery. 9V 221 kΩ 2.5 V LM385-2.5 Figure 8. Reference From a 9-V Battery 8.2.1 Design Requirements The key design requirement when using this device as a voltage reference is to supply the LM385 with a minimum Cathode Current (IZ), as indicated in Electrical Characteristics. 8.2.2 Detailed Design Procedure To generate a constant and stable reference voltage, a current greater than IZ(MIN) must be sourced into the cathode of this device. This can be accomplished using a current regulating device such as LM334 or a simple resistor. For a resistor, its value should be equal to or greater than (Vsupply - Vreference) ÷ IZ(MIN) . 8.2.3 Application Curve Input and Output Voltage − V 4 3 Output 24 kΩ 2 VI VO 1 0 5 Input 0 0 100 t − Time − µs 500 600 Figure 9.

For applications shunting high currents (30 mA maximum), pay attention to the cathode and anode trace lengths, and adjust the width of the traces to have the proper current density. 10 Layout 10.1 Layout Guidelines Figure 12 shows an example of a PCB layout of LMx85x-2.5. Some key Vref noise considerations are: • It is optional to connect a low-ESR, 0.1-μF (CL) ceramic bypass capacitor on the cathode pin node. • Decouple other active devices in the system per the device specifications. • Using a solid ground plane helps distribute heat and reduces electromagnetic interference (EMI) noise pickup. • Place the external components as close to the device as possible. This configuration prevents parasitic errors (such as the Seebeck effect) from occurring. • Do not run sensitive analog traces in parallel with digital traces. Avoid crossing digital and analog traces if possible and only make perpendicular crossings when absolutely necessary. 10.2 Layout Example Rsup NC 1 NC 2 NC 3 8 CATHODE 7 6 4 5 NC NC NC ANODE GND Vsup CL GND Figure 12.
