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.
FEATURES
• Two outputs, 3.3 V and 1.8 V or 2.5 V, built in a single package
• Output voltage accuracy: ±2%
• Peak output current: OUTPUT1: 1 A, OUTPUT2: 0.5 A
• On-chip saturation protector at low input voltage
• On-chip overcurrent limiter
• On-chip thermal protection
