LP2994-DDR Termination Regulator
General Instructions
The LP2985-XX is a 150 mA, fixed output voltage regulator designed to operate on battery power, providing very low dropout, low noise, and portable applications. The output voltage is preset to 1.8, 2.8, 3.0, 3.3, 3.6, or 5.0 V. LP2985-XX achieves design with optimized PNP process, unparalleled performance in all key specifications such as battery powered low supply current, low dropout design voltage, low power consumption, small size, fast dynamic response to line and load, high precision output etc., the regulator consists of an internal voltage reference, error amplifier, current driver limiter and thermal shutdown mechanism. The LP2985-XX is housed in a 5-pin SOT23-5 package.
