DESCRIPTION
The LP3992 regulator is designed to meet the
requirements of portable, battery-powered systems
providing an accurate output voltage, low noise, and
low quiescent current. Battery life will be prolonged
by the ability of the LP3992 to provide a 1.5V output
from the low input voltage of 1.9V. Additionally, when
switched to a shutdown mode via a logic signal at the
shutdown pin, the power consumption is reduced to
virtually zero. The LP3992 also features short-circuit
and thermal-shutdown protection.
The LP3992 is designed to be stable with space
saving ceramic capacitors as small as 1.0µF.
The device is available in a 5-pin, SOT-23 package.
Performance is specified for a -40°C to 125°C
temperature range.
For output voltages other than 1.5V and alternative
package options, contact TI.
