TO-252-3L
SN79Mxxx
3 Terminal 0.5A Negative Voltage Regulator
Description
The SN79Mxxx series are three-terminal Negative regulators providing
over 0.5A 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 SN79Mxxx series can be used with external components to
obtain adjustable voltages and Currents.
Application
Consumer and personal electronics
SMPS post-regulator / dc-to-dc modules
High-efficiency linear power supplies
TO-220F-3L

Absolute maximum ratings indicate limits beyond which damage to the component may occur. 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.

* Pulse testing techniques are used to maintain the junction temperature as close to the ambient
temperature as possible. Thermal effects must be taken into separately.
** This specification applies only for dc power dissipation permitted by absolute maximum ratings.
