THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR
The µPC24A00 Series is a low dropout voltage three terminal regulator that has realized a minimum voltage
differential between the I/O of no more than 1 V when the output current is 2 A through the employment of a PNP
transistor at the output stage.
Due to its ability to achieve a greater reduction in the power loss compared with conventional three-terminal
regulators, the µPC24A00 Series is ideal for use as the secondary side smoothing circuit of a power supply.

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the
verge of suffering physical damage, and therefore the product must be used under conditions that
ensure that the absolute maximum ratings are not exceeded.

CIN: 0.1 to 0.47 µF. Be sure to connect to prevent abnormal oscillation. When using capacitors, film capacitors with
excellent voltage and temperature characteristics are recommended. Be aware that some monolithic ceramic
capacitors have inferior temperature and voltage characteristics. When using a monolithic ceramic capacitor,
CIN requires a capacitor that can secure this capacity within the voltage and temperature range used.

Caution The recommended operating range may be exceeded without causing any problems provided that
the absolute maximum ratings are not exceeded. However, if the device is operated in a way that
exceeds the recommended operating conditions, the margin between the actual conditions of use
and the absolute maximum ratings is small, and therefore thorough evaluation is necessary. The
recommended operating conditions do not imply that the device can be used with all values at their
maximum values.
