NATIONAL SEMICONDUCTOR LP2954/LP2954A 5V Adjustable Micropower Low-Dropout Voltage Regulators Manual
Update: 30 September, 2023
The LP2954/LP2954A 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 pack- age. 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 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.
