LP38511MR-ADJ/NOPB

The LP38511MR-ADJ/NOPB is a single channel, fast transient response adjustable low dropout (LDO) linear voltage regulator in 8 pin HSOP (SO PowerPAD) package. This device offers highest performance in meeting AC and DC accuracy requirements for powering digital cores. The LP38511MR-ADJ uses a proprietary control loop that enables extremely fast response to change in line conditions and load demands. Output voltage DC accuracy is specified at 2.5% over line, load and full temperature range from -40°C to 125°C. This LDO regulator provides 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.

• Adjustable output voltage range from 0.5V to 5V
• Input supply voltage range from 2.25V to 5.5V
• Output load current of 800mA
• Maximum dropout voltage of 260mV at 800mA output current
• Stable with tiny 10µF ceramic capacitors
• 25dB of PSRR at 100KHz
• Less than 1μA of ground pin current with enable pin low
• Overtemperature and overcurrent protection
• Operating temperature range from -40°C to 125°C
