BIPOLAR ANALOG INTEGRATED CIRCUIT
µ PC37Mxx Series
TWO-OUTPUT POSITIVE VOLTAGE REGULATORS
★
DESCRIPTION
The µ PC37Mxx series is a series regulator with two outputs, OUTPUT1: 1 A and OUTPUT2: 0.5 A, built in a single
package. OUTPUT1 outputs 3.3 V or 2.5 V, and OUTPUT2 outputs 1.8 V or 2.5 V. This series can be used to realize
set miniaturization and component reduction due to the use of on MP-3 or MP-3Z package.
