LP2954 : The LP2954 is a 5V 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 LP2954 with a fixed 5V output is available in the three-lead TO-220 and TO-263 packages. The adjustable LP2954 is provided in an 8-lead surface mount, small outline package. The adjustable version also provides a resistor network 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 ve.

LP2954 : The LP2954 is a 5-V micropower LDO 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 LP2954 with a fixed 5-V output is available in three-pin TO-220 and DDPAK/TO-263 packages. The adjustable LP2954 is provided in an 8-pin, smalloutline SOIC package. The adjustable version also provides a resistor network which can be pin strapped to set the output to any voltage from to 1.23 V to 29 V. Reverse battery protection is provided for the IN pin. The tight line and load regulation (0.04.
