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. The LP2981 supports an output range of 1.2 V to 5.0 V (new chip). Additionally, the LP2981 (new chip) has a 1% output accuracy across load and temperature that can meet the needs of low.
• 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)
• Output current limiting and the.
