PRODUCTION DATA
For the legacy chip, aluminum electrolytics are not typically used with the LDO, because of the large physical size. These aluminum capacitors must meet the same ESR requirements over the operating temperature range, more difficult because of the steep ESR increase at cold temperature. An aluminum electrolytic can exhibit an ESR increase of as much as 50x when going from +20°C to ?40°C. Also, some aluminum electrolytics are not operational below ?25°C because the electrolyte can freeze.
