BIPOLAR ANALOG INTEGRATED CIRCUIT
µ PC37M31,37M32
TWO-OUTPUT POSITIVE VOLTAGE REGULATORS
DESCRIPTION
The µ PC37M31 and 37M32 are series regulators with two outputs, OUTPUT1: 1 A and OUTPUT2: 0.5 A, built in a
single package. OUTPUT1 outputs 3.3 V and OUTPUT2 outputs 1.8 V and 2.5 V. These regulators can be used to
realize set miniaturization and component reduction due to the use of on MP-3 or MP-3Z package.
