high voltage applications that require large input-to-output differentials, the LT3012 and LT3013 offer a very compact and thermally effective solution. The thermally enhanced DFN and TSSOP packages provide thermal resistances comparable to much larger conventional packages.
The LT3012 and LT3013 operate with very small, low cost ceramic output capacitors. They are stable with only a 3.3uF output capacitor, compared to older regulator devices of comparable output current and high voltage requiring 10uF to more than 100uF. These tiny external capacitors can be used without any necessary series resistance as is common with many other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting, and reverse-current protection.
The LT3012EDE (12-lead low profile 3mm x 4mm x 0.75mm DFN package) and LT3012EFE (16-lead thermally enhanced TSSOP package) are available from stock. 1,000-piece pricing is set at $2.05 and $2.20 each. The LT3013EDE and LT3013EFE are available from stock in the same packaging with 1,000-piece pricing set at $2.25 and $2.40 each.
