MIL-M-38510-118 Microcircuits, Linear, Adjustable, Negative, Voltage Regulators, Monolithic SiliconThis specification covers the detail requirements for three and four terminal monolithic silicon, adjustable, 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

NOTES:

1. Dimensions are in inches.

2. Metric equivalents are given for general information only and are based upon 1.00 inch = 25.4 mm.

3. (Four leads) φb applies between L1 and L2. φb1 applies between L2 and .500 (12.70 mm) from the reference plane. Diameter is uncontrolled in L1 and beyond .500 (12.70 mm) from the reference plane.

4. Four leads.

5. Measured from the maximum diameter of the product.

6. Leads having a maximum diameter .019 (.48 mm) measured in gaging plane .054 (1.37 mm) + .001 (.03 mm) -

.000 (.00 mm) below the base plane of the product shall be within .007 (.18 mm) of their true position relative to a maximum width tab.

7. The product may be measured by direct methods or by gage.
