LP2954A

The LP2954 is a 5V micropower voltage regulator with verylow quiescent current (90 µA typical at 1 mA load) and verylow dropout voltage (typically 60 mV at light loads and470 mV at 250 mA load current).

The quiescent current increases only slightly at dropout(120 µA typical), which prolongs battery life.

The LP2954 with a fixed 5V output is available in thethree-lead TO-220 and TO-263 packages. The adjustableLP2954 is provided in an 8-lead surface mount, small outlinepackage. The adjustable version also provides a resistor net-work which can be pin strapped to set the output to 5V.Reverse battery protection is provided.

The tight line and load regulation (0.04% typical), as well asvery low output temperature coefficient make the LP2954well suited for use as a low-power voltage reference.

Output accuracy is guaranteed at both room temperatureand over the entire operating temperature range.
