GENERAL DESCRIPTION
The SPX3819 is a positive voltage regulator
with a low dropout voltage and low noise
output. In addition, this device offers a very
low ground current of 800μA at 100mA output.
The SPX3819 has an initial tolerance of less
than 1% max and a logic compatible ON/OFF
switched input. When disabled, power
consumption drops to nearly zero. Other key
features include reverse battery protection,
current limit, and thermal shutdown. The
SPX3819 includes a reference bypass pin for
optimal low noise output performance. With its
very low output temperature coefficient, this
device also makes a superior low power
voltage reference.
The SPX3819 is an excellent choice for use in
battery-powered applications such as cordless
telephones, radio control systems, and
portable computers. It is available in several
fixed output voltage options or with an
adjustable output voltage.
This device is offered in 8 pin NSOIC, 8 pin
DFN and 5-pin SOT-23 packages.
