UPC2909T Datasheet | NEC

feature the ability to source 1 A of output current with a low dropout voltage of typically 0.7 V. The power dissipation of the µPC2900 series can be drastically reduced pared with the conventional three terminal positive voltage regulators that is constructed with NPN output transistor. Also, this series corresponds to the low voltage output (3 V, 3.3 V) which is not in the conventional low dropout regulators (µPC2400A series). FEATURES - Output current in excess of 1.0 A - Low dropout voltage VDIF = 0.7 V TYP. (at IO = 1 A) - On-chip overcurrent and thermal protection circuit - On-chip output transistor safe area protection circuit PIN CONFIGURATION (Marking Side) µPC2900HF Series: MP-45G µPC2900HB Series: MP-3 µPC2900T Series: MP-3Z 3 1: INPUT 2: GND 3: OUTPUT 1: 2: 3: 4: INPUT GND OUTPUT GND (Fin) The information in this document is subject to change without notice.
