New High-Temperature 200mA LDOs Withstand 80V Input up to 140°C
For 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 TSSOP package provides 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.
