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: 4.5 V to 16 V
- Maximum output current: 800 mA
- Adjustable output from 1.5 V to 5.1 V
- Low noise
- 1.0 μV rms total integrated noise from 100 Hz to 100 kHz
- 1.6 μV rms total integrated noise from 10 Hz to 100 kHz
- Noise spectral density: 1.7 nV√Hz from 10 kHz to 1 MHz
- Power supply rejection ratio (PSRR) at 400 mA load
- >90 dB from 1 kHz to 100 kHz, VOUT = 5 V
- >60 dB at 1 MHz, VOUT = 5 V
- Dropout voltage: 0.6 V at VOUT = 5 V, 800 mA load
- Initial voltage accuracy: ±1%
- Voltage accuracy over line, load and temperature: ±2%
- Quiescent current (IGND): 4.3 mA at no load
- Low shutdown current: 0.1 μA
- Stable with a 10 μF ceramic output capacitor
- 8-lead LFCSP package and 8-lead SOIC package
