ELM78L05CG Bipolar Three-terminal positive-voltage regulator ■General description ELM78L05 is three-terminal positive-voltage regulator which consists of internal short circuit current limiting and internal thermal overload protection. ■Features • • • • ■Application Maximum output current No external component Output voltage Package : 100mA • Linear regulator • Switch power supply • PCs : 5V : SOT-89 ■Maximum absolute ratings Input voltage Parameter Symbol Vin Power dissipation (air temperature) * Power dissipation (case temperature) * Storage temperature Operating junction temperature Lead temperature(soldering 10s.) Pd Pd Tstg Top Tlead Limit 30 500 (Top≤25°C) 300 (Top=70°C) 3125 (Top≤25°C) -65 to +150 0 to +125 260 Unit V mW mW °C °C °C * To avoid exceeding the design maximum virtual junction temperature, maximum absolute ratings should not be exceeded. Due to variations individual device electrical characteristics and thermal resistance, the built in thermal overload protection may be activated at power levels slightly above or below the rated dissipation. ■Recommended operating conditions Parameter Input voltage Output current (Max.)
