MIL-M-38510-117 Microcircuits, Linear, Adjustable, Positive, Voltage Regulators, Monolithic SiliconThis specification covers the detail requirements for three and four terminal monolithic silicon, adjustable, positive, 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

MIL-M-38510/11?C

3.4 Lead material and finish. Lead material and finish shall be in accordance with MIL-PRF-38535 (see 6.6).

3.5 Electrical performance characteristics. Unless otherwise specified, the electrical performance characteristics are as specified in table I and apply over the full operating ambient temperature range of -55°C to +125°C.

3.5.1 Stability. If the device is located an appreciable distance from the power supply filter, a solid tantalum bypass capacitor should be connected as close to the device VCC input as possible to suppress oscillation. A solid tantalum bypass

capacitor is recommended on the device output. Since load currents of less than 5 milliamperes may result in a loss of

voltage regulation, regulators should be preloaded with 5 milliamperes of load current in lightly loaded applications. In

applications where fast rising high current pulses are present, additional output capacitance of 20 µF or more shall be used.

3.5.2 Test limit. The test limits specified in tables I and III apply only for the stated test conditions (example, 2 percent duty cycle), which essentially keep the junction temperature constant. In most applications the junction temperature will greatly exceed the 25°C ambient or sink temperature; thus devices may not perform within the 25°C specified limits.

3.6 Electrical test requirements. Electrical test requirements for each device class shall be the subgroups specified in table II. The electrical tests for each subgroup are described in table III.

3.? Marking. Marking shall be in accordance with MIL-PRF-38535.

3.8 Microcircuit group assignment. The devices covered by this specification shall be in microcircuit group number 52 (see MIL-PRF-38535, appendix A).
