General Description
The LP2954 is a micropower voltage regulator with very
low quiescent current (90 μA typical at 1 mA load) and very
low dropout voltage (typically 60 mV at light loads and
470 mV at 250 mA load current).
The quiescent current increases only slightly at dropout
(120 μA typical), which prolongs battery life.
The adjustable LP2954AIM is provided in an 8-lead surface mount, small outline
package. 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 as
very low output temperature coefficient make the LP2954
well suited for use as a low-power voltage reference.
Output accuracy is guaranteed at both room temperature
and over the entire operating temperature range.

- PLEASE NOTE!
- These parts are now obsolete, they came to us as part of a lot of surplus stock from a large ‘MILSPEC’ type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however pristine, stored with us still in their original packaging and ‘as new’ in all respects, the photographs are representative of their excellent condition, and, as with all our products they come with a full guarantee.
