Adjustable 500mA LDO voltage regulator operates from -55 up to +225°C
Output voltage can be adjusted anywhere between 1.2V and 3.3V. It is packaged in a tiny SMD ceramic package TDFP 5×5.5mm, guaranteed for operation from -55°C up to +225°C. Total output voltage accuracy under all operating conditions including load, line and temperature variations is guaranteed to be better than ±5%. A special care has been taken of optimizing the response to line and load transients, which makes the chip suitable to supply high temperature microprocessors and memories. The regulator is self-protected with a built-in over-current limitation combined with a thermal protection which becomes effective above 250°C. The circuit typically requires an external 2.2µF capacitor and a 2-resistor bridge for feedback (output voltage setting).
