Semtech 1N499x 5W Voltage Regulators provide low dynamic impedance and low reverse leakage currents. These regulators operate at -55°C to 175°C operating temperature range and 6.8V to 300V reverse voltage range (VR). The 1N499x voltage regulators feature low dynamic impedance and a hermetic seal. These voltage regulators are used in 5W applications and are qualified to MIL-PRF-19500/356.
