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

* 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.

–
1) CIN should be required if regulators are located far from power supply filter
2) CO improves output stability and transient response
3) To specify an output voltage, substitute voltage value for “xx”
