LP2981A-50
Description
The LP2981 is a fixed-output, low-dropout (LDO) voltage regulator supporting an input voltage range from 2.5 V to 16 V (for new chip only) and up to 100 mA of load current.
Key Features
- Input Voltage (VIN) Range: – Legacy chip: 2.2 V to 16 V – New chip: 2.5 V to 16 V
- Output Voltage (VOUT) Range: 1.2 V to 5.0 V
- Output Voltage (VOUT) Accuracy
- Output Voltage (VOUT) accuracy over load, and
- Output current: Up to 100 mA
- Low IQ (new chip): 69 μA at ILOAD = 0 mA
- Low IQ (new chip): 620 μA at ILOAD = 100 mA
- Shutdown current over temperature
- Output current limiting and thermal protection
- Stable with 2.2-µF ceramic capacitors (new chip)
Applications
- Electricity meters
