SN79xxx 3 Terminal 1A Negative Voltage Regulator Semiconductor http:// www.auk.co.kr Description The SN79xxx series are three-terminal Negative regulators providing over 1A output current with internal current limiting, thermal shutdown and safe area protection. These regulators are useful in a wide range of applications. Although they are just fixed voltage regulators, the SN79xxx series can be used with external components to obtain adjustable voltages and Currents. TO-252-3L Application Consumer and personal electronics SMPS post-regulator / dc-to-dc modules High-efficiency linear power supplies Features and Benefits Output Current up to 1.0A TO-220F-3L Output Voltage : -5, -6, -8, -9, -10, -12, -15, -18, -24V Built in OVP, CLP circuit.

Electrical specifications do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(max) , the junction-to-ambient thermal resistance, JA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD(max) = (TJ(max) – TA) ÷ JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
