Analog Devices LT3073 | Demoboard EVAL-LT3073-AZ
Evaluating the LT3073 3A, Ultra-Low Noise, High PSRR, 45 mV Dropout Ultra-Fast Linear Regulator
Overview
| Topology | Other Topology |
| Input voltage | 0.6-5.5 V |
| Output 1 | 4.2 V / 3 A |
Description
The EVAL-LT3073-AZ evaluation board features the LT3073, a 3 A, ultra-low noise, high power-supply rejection ratio (PSRR), 45 mV dropout ultra-fast linear regulator. The input voltage (VIN) range for the VIN power is from 0.6 V to 5.5 V. There are jumpers to set a 3-bit trilevel code that determines the output voltage (VOUT) at preprogrammed levels that range from 0.5 V to 4.2 V. The maximum output current is 3 A. The EVAL-LT3073-AZ requires an external BIAS voltage (VBIAS) that is at least 1.2 V higher than VOUT and is between 2.375 V and 5.5 V.
Features
- Ultra-low RMS Noise: 1.2μVRMS (10Hz to 100kHz)
- Ultra-low Spot Noise: 3nV/√Hz at 10kHz
- Ultra-low 1/f Noise: 7μVP-P from 0.1Hz to 10Hz
- High-Frequency PSRR: 52dB at 1MHz
- Ultra-fast Transient Response
- Dropout Voltage: 45mV Typical
- Digitally Programmable VOUT: 0.5V to 4.2V
- Output Tolerance: ±1.5% Over Line, Load, and Temperature
- Precision Current Monitor: ±3% accuracy at 3A
- Programmable Current Limit: ±3% at 3A
- Input Range: 0.6V to 5.5V
- Digital Output Margining: ±2.5%
- Stable with Ceramic Output Capacitors (10μF Minimum)
- Parallel Multiple Devices for Higher Current
- VIOC Pin to Control Upstream Switching Converter
- Precision Enable/Under Voltage Lock Out (UVLO)
- Power Good (PG) Flag
- Temperature Monitor
- 22-Lead (3mm x 4mm) LQFN Package
