DESCRIPTION  
The LP2951-xx-Q1 devices are bipolar, low-dropout voltage regulators that can accommodate a wide input  
supply-voltage range of up to 35 V. The 8-pin LP2951-xx-Q1 is able to output either a fixed or adjustable output  
from the same device. By tying the OUTPUT and SENSE pins together, and the FEEDBACK and VTAP pins  
together, the LP2951-xx-Q1 outputs a fixed 5 V and 3.3 V (depending on the version). Alternatively, by leaving  
the SENSE and VTAP pins open and connecting FEEDBACK to an external resistor divider, the output can be set  
to any value between 1.235 V to 30 V.  
The 8-pin LP2951-xx-Q1 also offers additional functionality that makes it particularly suitable for battery-powered  
applications. For example, a logic-compatible shutdown feature allows the regulator to be put in standby mode  
for power savings. In addition, there is a built-in supervisor reset function in which the ERROR output goes low  
when VOUT drops by 6% of its nominal value for whatever reasons – due to a drop in VIN, current limiting, or  
thermal shutdown.  
The LP295x-xx-Q1 devices are designed to minimize all error contributions to the output voltage. With a tight  
output tolerance (0.5% at 25°C), a very low output voltage temperature coefficient (20 ppm typical), extremely  
good line and load regulation (0.3% and 0.4% typical), and remote sensing capability, the parts can be used as  
either low-power voltage references or 100-mA regulators.  
For the most-current package and ordering information, see the Package Option Addendum at the end of this  
document, or see the TI Web site at www.ti.com.
