LP2954/LP2954A 5V and Adjustable Micropower Low-Dropout Voltage Regulators June 1999 LP2954/LP2954A 5V and Adjustable Micropower Low-Dropout Voltage Regulators General Description 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...
