DESCRIPTION/ORDERING INFORMATION  
The LP2950 and LP2951 devices are bipolar, low-dropout voltage regulators that can accommodate a wide input  
supply-voltage range of up to 30 V. The easy-to-use, 3-pin LP2950 is available in fixed-output voltages of 5 V,  
3.3 V, and 3 V. However, the 8-pin LP2951 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 outputs a fixed 5 V, 3.3 V, or 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 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 LP2950 and LP2951 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.
