µ
PC2900 Series
THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR
The
µ
PC2900 series of low dropout voltage three terminal positive regulators is constructed with PNP output
transistor. The
µ
PC2900 series 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
µ
PC2900 series can be drastically reduced compared 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 (
µ
PC2400A series).
FEATURES
• Output current in excess of 1.0 A
• Low dropout voltage V
DIF
= 0.7 V TYP. (at I
O
= 1 A)
• On-chip overcurrent and thermal protection circuit
• On-chip output transistor safe area protection circuit
