Press Release Summary:
Featuring input voltage range of 1.6-45 V, Model LT3060 delivers adjustable output voltages from 0.6-44.5 V and up to 100 mA continuous output current with 300 mV dropout voltage at full load. Single capacitor provides programmable ultra-low-noise operation of 30 µVrms across bandwidth of 10 Hz to 100 kHz. Available in 2 x 2 mm DFN-8 and 8-lead ThinSOT packages, IC includes reference soft start functionality, which prevents output voltage overshoot at turn-on.
Original Press Release:
45V Input 100mA LDO Offers 30µVRMS Noise & Output Down to 0.6V
MILPITAS, CA -- Linear Technology Corporation announces the LT3060, a high voltage, low noise, low dropout voltage linear regulator. The IC delivers up to 100mA continuous output current with a 300mV dropout voltage at full load. The LT3060 features a wide input voltage range of 1.6V to 45V, delivering adjustable output voltages from 0.6V to 44.5V. A single capacitor provides both programmable ultra-low noise operation -- only 30µVRMS across a wide bandwidth of 10Hz to 100kHz - and reference soft start functionality, preventing output voltage overshoot at turn-on.
The LT3060's output voltage tolerance is highly accurate at ±2% over line, load and temperature. The IC's wide input and output voltage ranges, fast transient response, low quiescent current of 40µA (operating) and <1µA (in shutdown) make it an excellent choice for portable battery-powered systems that require optimum run time, and usage in automotive, industrial and avionic power supply applications.
The LT3060 operates with a very small, low cost, ceramic output capacitor, optimizing stability and transient response. It is stable with only a 2.2µF output capacitor. These tiny external capacitors can be used without the necessary addition of series resistance (ESR) as is common with many other regulators. The LT3060's internal protection circuitry includes reverse-battery protection, reverse-output protection, reverse-current protection, current limit with foldback and thermal limiting.
The LT3060EDC, LT3060IDC, LT3060ETS8 and LT3060ITS8 are housed in 8-lead 2mm x 2mm DFN and 8-lead ThinSOT(TM) packages, respectively, offering a compact footprint. The "E" and "I" grade versions are available from stock with an operating junction temperature of -40°C to +125°C and are priced at $1.21 and $1.33 each, respectively. The LT3060HTS8 "H" grade and LT3060MPTS8 "MP" grade are available from stock and offered in the ThinSOT package, with respective operating junction temperatures of -40°C to +150°C and -55°C to +125°C, and are priced at $1.67 and $4.34 each, respectively.
