LP2951-xx-Q1 Adjustable Micropower Voltage Regulators With Shutdown

LP2951-33QDRGRQ1  原装  低压差稳压器  的 概述：

The LP2951-xx-Q1 devices are bipolar, low-dropout voltage regulators that can accommodate a wide input supply-voltage range of up to 30 V. The 8-pin LP2951-xx-Q1 devices are 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 devices output 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-xx-Q1 devices also offer additional functionality that makes them 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. LP2951-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 lowpower voltage references or 100-mA regulators.
