LP2980 Micropower SOT, 50 mA Ultra Low-Dropout Regulator General Description The LP2980 is a 50 mA, fixed-output voltage regulator de-signed specifically to meet the requirements of battery-pow-ered applications. Linear Regulators (LDO Regulators) ABLIC’s linear regulators (LDO regulators) feature the low current consumption, high-withstand voltage, wide operating voltage range, super-small packages, and high ripple rejection ratio. Hi Andy, LP2980 is an old device and unfortunately dose not have a model ready for simulation since it wasn't a common practice to have a simulation model when the device was released. Designed specifically for battery-operated sys-tems, the TC1014’s CMOS construction eliminates wasted ground current, significantly extending battery life. Description: Product Details The LTC1736 is a synchronous step-down switching regulator controller optimized for CPU power.The output voltage is programmed by a 5-bit digital-to-analog converter (DAC) that adjusts the output voltage from 0.925V to 2.00V according to Intel mobile VID specifications . We're using the 5V power supply to generate the 3.3V supply, it does that by essentially 'eating' the 5-3.3 = 1.7V difference and dissipating the power difference in heat.
