Part Details:

LM2930 June 2005 3-T LM2930 erminal 3-Terminal Positive RegulatorGeneral Description Features The LM2930 3-terminal positive regulator features an ability n Input-output differential less than 0.6V to source 150 mA of output current with an input-output n Output current in excess of 150 mA Positive differential of 0.6V or less. Efficient use of low input voltages n Reverse battery protection obtained, for example, from an automotive battery during n 40V load dump protection cold crank conditions, allows 5V circuitry to be properly n Internal short circuit current limit powered with supply voltages as low as 5.6V. Familiar regu- n Internal thermal overload protection lator features such as current limit and thermal overloadprotection are also provided. n Mirror-image insertion protection Regulator n P+ Product Enhancement tested Designed originally for automotive applications, the LM2930and all regulated circuitry are protected from reverse batteryinstallations or 2 battery jumps. During line transients, such Voltage Range as a load dump (40V) when the input voltage to the regulator j LM2930T-5.0: 5V can momentarily exceed the specified maximum operatingvoltage, the regulator will automatically shut down to protect j LM2930T-8.0: 8V both internal circuits and the load. The LM2930 cannot be j LM2930S-5.0: 5V harmed by temporary mirror-image insertion. j LM2930S-8.0: 8V Fixed outputs of 5V and 8V are available in the plasticTO-220 and TO-263 power packages.
