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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

6.5   Abbreviations, symbols, and definitions.  The abbreviations, symbols, and definitions used herein are defined in

MIL-PRF-38535, MIL-HDBK-1331, and as follows:

6.5.1  Line regulation.  The change in output voltage for a specified change in input voltage (VRLINE).

6.5.2  Load regulation.  The change in output voltage for a specified change in load current (VRLOAD).

6.5.3  Ripple rejection.  The ratio of the peak to peak input ripple voltage to the peak to peak output ripple voltage

(VOUT / VIN).

6.5.4  Output noise voltage.  The rms output noise voltage with constant load and no input ripple (VNO).

6.5.5  Standby current drain.  The supply current drawn by the regulator with no output load or with a 1 kν output load.

6.5.6  Input voltage range.  The range of supply voltage over which the regulator will operate.

6.5.7  Output voltage range.  The range of output voltage over which the regulator will operate.

6.5.8  Transient response.  The closed-loop step function response of the regulator under small-signal conditions.

6.6  Logistic support.  Lead materials and finishes (see 3.3) are interchangeable.  Unless otherwise specified, microcircuits acquired for Government logistic support will be acquired to device class B (see 1.2.2), lead material and finish A (see 3.4).  Longer length leads and lead forming should not affect the part number.

6.7  Substitutability.  The cross-reference information below is presented for the convenience of users.  Microcircuits covered by this specification will functionally replace the listed generic-industry type.  Generic-industry microcircuit types may not have

equivalent operational performance characteristics across military temperature ranges or reliability factors equivalent to MIL-M-38510 device types and may have slight physical variations in relation to case size.  The presence of this information should not be deemed as permitting substitution of generic-industry types for MIL-M-38510 types or as a waiver of any of the provisions of MIL-PRF-38535.
