SA56613-XX
5 V, 150 mA LDO and independent delayed RESET

2002 Mar 25
853–2331 27919
DESCRIPTION
The SA56613-XX has a precise fixed 5 V output with a typical
accuracy of
±2% to provide very low dropout and low noise in
CD-ROM drives, battery-operated systems, and portable computers
applications. This regulator consists of an internal voltage reference,
an error amplifier, a driver with current limiter and a thermal
shutdown.
An Active-LOW RESET is asserted when the regulator output
voltage (VOUT) falls below the reset detection voltage threshold. The
SA56613-XX is available with fixed detection threshold voltages of
4.2, 4.5, and 4.7 V. The RESET output remains low for 1 ms (typical)
when a 10 nF capacitor is connected to CD pin. The reset time delay
can be adjusted by replacing capacitance values from CD pin to
Ground.
The device is available in the small SO8 package.
