TEXAS INSTRUMENTS LP2954AIS/NOPB 固定电压稳压器, LDO, -20V至30V, 470mV压差, 5V输出, 250mA输出, TO-263-3
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, small-outline 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% 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 ensured at both room temperature and over the entire operating temperature range.
