See all from this product rangeProduct Overview
The LT3045IDD#PBF is a high performance, ultra-low noise, ultra-high PSRR low dropout (LDO) linear regulator in 10 pin DFN package. The ultra-low noise and ultra-high PSRR architecture of this device is useful powering noise sensitive applications. Designed as a precision current reference followed by a high performance voltage buffer, the LT3045 can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB. Operating quiescent current is nominally 2.2mA and drops to <<1µA in shutdown. The LT3045's wide output voltage range (0V to 15V) while maintaining unity gain operation provides virtually constant output noise, PSRR, bandwidth and load regulation independent of the programmed output voltage. It is used in RF power supplies, PLLs, VCOs, mixers, LNAs, PAs, very low noise instrumentation, high speed/high precision data converters, precision power supplies & post regulator for switching supplies.
- Ultra-low RMS noise of 0.8µVrms (10Hz to 100KHz) and ultra-low Spot noise of 2nV/√Hz at 10KHz
- 1.8V to 20V input voltage range, 1MHz high bandwidth and ultra-high PSRR of 76dB at 1MHz
- Programmable current limit and fast start-up capability
- Single resistor programs output voltage, single capacitor improves noise and PSRR
- 100µA SET pin current, ±1% initial accuracy, stable with a minimum 10µF ceramic output capacitor
- Programmable current limit and programmable power good
- Fast start-up capability, precision enable/UVLO and thermal limit with hysteresis
- Supplies 500mA output current at a typical 260mV dropout voltage
- Reverse battery protection, reverse current protection and internal current limit with foldback
- Operating temperature range from -40°C to 125°C
