LP2985
Overview
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).
- 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
