1 / 14 page © Semiconductor Components Industries, LLC, 2004 January, 2004 − Rev. 8 1 Publication Order Number: CS8120/D CS8120 5.0 V, 300 mA Linear Regulator with RESET and ENABLE The CS8120 is a 5.0 V, 300 mA precision linear regulator with two microprocessor compatible control functions and protection circuitry included on chip. The composite NPN−PNP output pass transistor assures a lower dropout voltage (1.0 V @ 200 mA) without requiring excessive supply current (2.5 mA). The CS8120’s two logic control functions make this regulator well suited to applications requiring microprocessor−based control at the board or module level. ENABLE controls the output stage. A high voltage (> 2.9 V) on the ENABLE lead turns off the regulator’s pass transistor and sends the IC into Sleep mode where it draws only 250 mA. The RESET function sends a RESET signal when the IC is powering up or whenever the output voltage moves out of regulation. The RESET signal is valid down to VOUT = 1.0 V. The CS8120 design optimizes supply rejection by switching the internal bandgap reference from the supply input to the regulator output as soon as the nominal output voltage is achieved. Additional on chip filtering enhances rejection of high frequency transients on all external leads. The CS8120 is fault protected against short circuit, over voltage and thermal runaway conditions.
