LP2954AIM/NOPB

TEXAS INSTRUMENTS  LP2954AIM/NOPB  电压稳压器, LDO, 可调, -20V至30V输入, 470mV压差, 1.23V至29V/250mA输出, SOIC-8

The is a micro-power Voltage Regulator with very low quiescent current and very low-dropout voltage. The quiescent current increases only slightly at dropout, which prolongs battery life. The adjustable version provides a resistor network which can be pin strapped to set the output to 5V. The tight line and load regulation, 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.
