LP2981-33
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
- ±0.75% for A-Grade legacy chip - ±1.25% for standard-grade legacy chip - ±0.5% for new chip (A grade and standard grade)
- Output Voltage (VOUT) accuracy over load, and temperature: ±1% (new chip)
- 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
- < 1 μA (legacy chip) - ≤ 1.75 μA (new chip)
