| OM7805SM OM7812SM OM7815SM SURFACE MOUNT POSITIVE FIXED VOLTAGE REGULATOR Three Terminal, Fixed Voltage, 1.0 Amp Precision Positive Regulator In A Hermetic Surface Mount Package FEATURES * * * * * * Hermetic Surface Mount Package Output Voltages: +5V, +12V, +15V Output Voltages Set Internally To 2% Built-In Thermal Overload Protection Short Circuit Current Limiting Product Is Available Hi-Rel Screened DESCRIPTION This three terminal positive regulator is supplied in a hermetically sealed surface mount package. All protective features are designed into the circuit, including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver 1.0 amp of output current. This unit features internally trimmed voltages to 2% of nominal voltage. Standard voltages are +5V, +12V, and +15V. These units are ideally suited for Military applications where a hermetic surface mount package is required.

Note 1: Load and line regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used. Changes in output voltage due to heating effects must be taken into account separately. Note 2: Short Circuit protection is only assured up to VIN = 35V Note 3: If not tested, shall be guaranteed to the specified limits. The * denotes the specifications which apply over the full operating temperature range. If not noted TA = 25C |
