Sipex’s SPX2969 is a low dropout linear regulator with integrated PNP pass transistor. The part
is designed for automotive environment, and thus can withstand up to 45V and 125
°
C
temperature range. The output voltage is set at a fixed 5V, and the part is guaranteed to deliver
at least 150mA. The SPX2969 provides multiple protection mechanisms, including over-
temperature and over-current conditions. The part has a built-in reset circuit to monitor when the
output voltage is below 4.65V. The reset voltage threshold can be programmed down to 3.5V
using an external resistor voltage divider, while the reset timing can be programmed via an
external capacitor. A built in comparator compares the signal of the pin SI, normally fed by a
voltage divider from the input voltage, with the reference and gives an early warning on the pin
SO. Both the sense output and the reset output delay signals contain integrated 20k
Ohm
pull up
resistors. The part is available in three package types: 8 Pin and 14 Pin nSOIC or 20 Pin wSOIC
packages.
