Note:

All parameters are guaranteed in the junction temperature range -40 °C to 150 °C (unless otherwise specified);

the L99VR03 device is still operative and functional at higher temperatures (up to 175 °C). Parameters limit at

higher junction temperature than 150 °C may change respect to what is specified as per the standard

temperature range. Device functionality at high junction temperature is guaranteed by characterization.

All parameters are guaranteed by design for VO not reported in test condition.

Minimum input voltage values are achievable adopting an input ceramic capacitor: C5750X7R2A475M230KA -

ceramic capacitor multistrate SMD, 4.7 μF, 100 V, ±20%, X7R, C series.
