SN79Lxxx 3 Terminal Negative Voltage Regulator [100mA] Semiconductor http:// www.auk.co.kr Description The SN79Lxxx series are three-terminal Negative regulators providing over 100mA 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 SN79Lxxx series can be used with external components to obtain adjustable voltages and Currents. It also contains the TCE Cell to protect internal circuit from ESD damage.

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, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD(max) = (TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
