They NMF4809DC 48 9 100 900 62 86 283 DIP Contact Murata are ideal for situations where the input voltage is NMF4812DC 48 12 83 1000 62 108 162 DIP Contact Murata not tightly controlled. The output trim pin makes NMF4815DC 48 15 67 1000 62 127 135 DIP Contact Murata the device particularly suitable for applications requiring a programmable output voltage. The 5V NMF4805SC 48 5 100 500 50 51 200 SIP Contact Murata output version can be used to give a regulated NMF4809SC 48 9 100 900 62 86 283 SIP Contact Murata output, adjustable between 1.2V and 5.0V with a NMF4812SC 48 12 83 1000 62 108 162 SIP Contact Murata single resistor.

The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up. 1. Calculated using MIL-HDBK-217F with nominal input voltage at full load. 2. Supply voltage must be discontinued at the end of the short circuit duration.
