The LP2985 is a fixed-output, wide-input, low-noise, low-dropout voltage regulator supporting an input voltage range from 2.5 V to 16 V and up to 150 mA of load current. The LP2985 supports an output range of 1.2 V to 5.0 V (for new chip). Additionally, the LP2985 (new chip) has a 1% output accuracy across load, and temperature that can meet the needs of l.
• VIN range (new chip): 2.5 V to 16 V
• VOUT range (new chip):
– 1.2 V to 5.0 V (fixed, 100-mV steps)
• VOUT accuracy:
– ±1% for A-grade legacy chip
– ±1.5% for standard-grade legacy chip
– ±0.5% for new chip only
• ±1% output accuracy over load, and temperature for new chip
• Output current: Up to 150 mA
• Low IQ (new chip): 71 μA at ILOAD = 0 mA
• Low IQ (new chip): 750 μA at ILOAD = 150 mA
• Shutdown current:
– 0.01 μA (typ) for legacy chip
– 1.12 μA (typ) for new chip
• Low noise: 30 μVRMS with 10-nF bypass capacitor
• Output current limiting and thermal protection
• Stable with 2.2-µF cer.
