| MICROCIRCUIT DATA SHEET MNLM185B-X REV 0A0 Original Creation Date: 08/15/95 Last Update Date: 02/03/99 Last Major Revision Date: 08/15/95 ADJUSTABLE MICROPOWER VOLTAGE REFERENCE General Description The LM185B is a micropower 3-terminal adjustable band-gap voltage reference diode. Operating from 1.24 to 5.3V and over a 10 uA to 20 mA current range, it features exceptionally low dynamic impedance and good temperature stability. On-chip trimming is used to provide tight voltage tolerance. Since the LM185B band-gap reference uses only transistors and resistors, low noise and good long-term stability result. Careful design of the LM185B 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 LM185B 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.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. 3 MNLM185B-X REV 0A0 MICROCIRCUIT DATA SHEET Electrical Characteristics DC PARAMETERS SYMBOL Vref PARAMETER Reference Voltage Ir = 100uA CONDITIONS NOTES PINNAME MIN 1.228 1.215 Ir = 9uA Ir = 10uA Ir = 1mA 1.228 1.215 1.228 1.215 Ir = 20mA 1.228 1.215 Vr = 5.3V, Ir = 100uA 1.228 1.215 Vr = 5.3V, Ir = 45uA Vr = 5.3V, Ir = 50uA Vr = 5.3V, Ir = 1.0mA 1.288 1.215 1.288 1.215 Vr = 5.3V, Ir = 20mA 1.288 1.215 Delta Vref/Delta Ir Reference Voltage Change with Current 9uA < Ir < 1mA 10uA < Ir < 1mA 1mA < Ir < 20mA 1mA < Ir < 20mA Vr = 5.3V, 45uA < Ir < 1mA Vr = 5.3V, 50uA < Ir < 1mA Vr = 5.3V, 1mA < Ir < 20mA Vr = 5.3V, 1mA < Ir < 20mA Delta Vref/Delta Vo Reference Voltage Change with Output Voltage Vr = 5.3V, Ir = 100uA MAX 1.252 1.255 1.252 1.255 1.252 1.255 1.252 1.255 1.252 1.255 1.252 1.255 1.252 1.255 1.252 1.255 1 1.5 10 20 1 1.5 10 20 3 6 UNIT V V V V V V V V V V V V V V V V mV mV mV mV mV mV mV mV mV mV SUBGROUPS 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 4 MNLM185B-X REV 0A0 MICROCIRCUIT DATA SHEET Electrical Characteristics DC PARAMETERS(Continued) SYMBOL If PARAMETER Feedback Current Ir = 9uA Ir = 10uA Ir = 20mA CONDITIONS NOTES PINNAME MIN MAX 20 25 20 25 Vr = 5.3V, Ir = 45uA Vr = 5.3V, Ir = 50uA Vr = 5.3V, Ir = 20mA 20 25 20 25 Ic Minimum Operating Current Vr = Vref 1 1 Vr = 5.3V 1 1 Note 1: Functional Test. 9 10 45 50 UNIT nA nA nA nA nA nA nA nA uA uA uA uA SUBGROUPS 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 1 2, 3 5 MNLM185B-X REV 0A0 MICROCIRCUIT DATA SHEET Graphics and Diagrams GRAPHICS# 05886HRB2 06175HRB2 E20ARE H02ARE P000188A P000366B DESCRIPTION METAL CAN,TO-46,2LD,.100 DIA P.C.
