SN78Lxxx 3 Terminal Positive Voltage Regulator e Semiconductor http:// www.auk.co.kr Description The SN78Lxxx series are three-terminal positive regulators providing over 150mA 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 SN78Lxxx 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.
