CS8120 - 5V/ 300mA Linear Regulator with and ENABLE RESET

General Description

The CS8120 is a 5V, 300mA 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 (1V @ 200mA) without requiring excessive supply current (2.5mA).

Key Features

  • s 5V ± 4% Output Voltage 300mA s Low Dropout Voltage (1V @ 150mA) s Low Quiescent Current (2.5mA @ IOUT = 150mA) s µP Compatible Control Functions RESET ENABLE 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 = 1V. 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.

CS8120 CS8120 5V, 300mA Linear Regulator with RESET and ENABLE Description The CS8120 is a 5V, 300mA 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 (1V @ 200mA) without requiring excessive supply current (2.5mA). The CS8120Õs two logic control functions make this regulator well suited to applications requiring microprocessorbased control at the board or module level. ENABLE controls the output stage. A high voltage (>2.9V) on the ENABLE lead turns off the regulatorÕs pass transistor and sends the IC into Sleep mode where it draws only 250µA.
