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.
