Output Regulation and Accuracy
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.
