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
- Low noise: 11 μV rms independent of fixed output voltage
- PSRR of 88 dB at 10 kHz, 68 dB at 100 kHz, 50 dB at 1 MHz, VOUT ≤ 5 V, VIN = 7 V
- Input voltage range: 2.7 V to 40 V
- Maximum output current: 200 mA
- Initial accuracy: ±0.8%
- Accuracy over line, load, and temperature
- −1.2% to +1.5%, TJ = −40°C to +85°C
- ±1.8%, TJ = −40°C to +125°C
- Low dropout voltage: 200 mV (typical) at a 200 mA load, VOUT = 5 V
- User programmable soft start (LFCSP and SOIC only)
- Low quiescent current, IGND = 50 μA (typical) with no load
- Low shutdown current: 1.8 μA at VIN = 5 V, 3.0 μA at VIN = 40 V
- Stable with a small 2.2 μF ceramic output capacitor
- Fixed output voltage options: 1.8 V, 2.5 V, 3.3 V, 3.8 V, and 5.0 V
- 15 standard voltages between 1.2 V and 5.0 V are available
- Adjustable output from 1.2 V to VIN – VDO, output can be adjusted above initial set point
