NJM78LxxS 3-Terminal Voltage Regulators Nisshinbo (New Japan Radio) NJM78LxxS 3-Terminal Voltage Regulators are designed with improvements such as output voltage accuracy, operating temperature range, and MLCC correspondence. These regulators operate at 100mA output current and offer high ripple rejection with an overcurrent protection circuit. The NJM78LxxS voltage regulators provide thermal shutdown and are available in the SOT-89-3 package.
