The Analog Devices Low Dropout (LDO) Linear Regulators offer fast transient response, excellent line and load regulation, and they have a wide input voltage range.
Feature
- Input voltage range: 3.3 V to 20 V
- Maximum output current: 500 mA
- Low Noise: 15 μV rms for fixed output versions
- PSRR Performance of 60 dB at 10 kHz, VOUT = 3.3 V
- Reverse current protection
- Low dropout voltage: 350 mV at 500 mA
- Initial accuracy: ±0.8%
- Accuracy over line, load, and temperature
- −2% to +1%, TJ = −40°C to +125°C
- −1.25% to +1%, TJ = 0°C to +85°C
- Low quiescent current (VIN = 5 V), IGND = 900 μA with 500 mA load
- Low shutdown current: <40 μA at VIN = 12 V, stable with small 1 μF ceramic output capacitor
- 7 fixed output voltage options: 1.5 V, 1.8 V, 2.5 V, 3 V, 3.3 V, 5 V, and 9 V
- Adjustable output from 1.22 V to VIN − VDO
