www.ti.com SNOSAU6E – NOVEMBER 2007 – REVISED APRIL 2013 LP38511-1.8 800 mA Fast-Transient Response Low-Dropout Linear Voltage Regulator with
Error Flag
Check for Samples: LP38511 FEATURES DESCRIPTION The LP38511-1.8 Fast-Transient Response LowDropout Voltage Regulator offers the highestperformance in meeting AC and DC accuracy
requirements for powering Digital Cores. The
LP38511-1.8 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 В±2.5% over line, load and full
temperature range from -40В°C to +125В°C. The
LP38511-1.8 is designed for inputs from the 2.5V,
3.3V, and 5.0V rail, is stable with 10uF ceramic
capacitors, and has a fixed 1.8V output. An Error Flag
feature monitors the output voltage and notifies the
system processor when the output voltage falls more
than 15% below the nominal value. The LP38511-1.8
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. 1 2 2.25V to 5.5V Input Voltage Range
