MIL-M-38510-148 Microcircuits, Linear, Adjustable, Precision Voltage Reference, Shunt Regulator, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, precision voltage reference. Two product assurance classes and a choice of case outlines and lead finishes are provided and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3
