LP38512 Low Dropout Linear Voltage Regulator

LP38512-ADJ (Adjustable) and LP38512-1.8 (Fixed 1.8 V Output)

LP38512 - 1.5A Fast-Transient Response Texas Instruments' LP38512-ADJ and LP38512-1.8 fast-transient response low-dropout voltage regulators offer high-performance that meets AC and DC accuracy requirements for powering digital cores. They both use a proprietary control loop that enables extremely fast response to change in line conditions and load demands. Output voltage DC accuracy is guaranteed at 2.5% over line, load and full temperature range from -40°C to +125°C.

The LP38512-ADJ is designed for inputs from the 2.5 V, 3.3 V, and 5.0 V rail is stable with 10 µF ceramic capacitors. The LP38512-ADJ has an adjustable output voltage, while the LP38512-1.8 has a fixed 1.8 V output. The LP38512-1.8 has an error flag feature that monitors the output voltage and notifies the system processor when the output voltage falls more than 15% below the nominal value. Both provide excellent transient performance to meet the demand of high performance digital core ASICs, DSPs, and FPGAs found in highly-intensive applications such as servers, routers/switches, and base stations.
