MIL-M-38510-115 Microcircuits, Linear, Negative, Voltage Regulators, Monolithic SiliconThis specification covers the detail requirements for fixed output, monolithic silicon, negative, voltage regulators. Two product assurance classes and a choice of case outlines and lead finish are provided for each type 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.
