DATA SHEET

MOS INTEGRATED CIRCUIT

μ PD121WxxA Series

HIGH CURRENT 1.5 A

GENERAL-PURPOSE CMOS REGULATOR

DESCRIPTION

The μ PD121WxxA series is general-purpose CMOS regulators which have 1.5 A output current capacity. These

products are suitable for power supply of large-scale ASICs etc. By ON/OFF function, the power consumption can be

kept low level at the time of off-state. This series of regulator has 3 fixed output voltage type 1.8 V, 2.5 V, 3.3 V, and

adjustable output voltage type (1.8 to 3.3 V).

FEATURES

• Output Current: 1.5 A

• Output Voltage: 1.8 V, 2.5 V, 3.3 V (Fixed type) / 1.8 to 3.3 V (Adjustable type)

• Output Voltage Tolerance: VO ± 2.0% (TJ = 25°C)

• Dropout Voltage: VDIF = 1.0 V MAX. (IO = 1.5 A)

• Quiescent Current: 150 μ A TYP. (IO = 0 A)

• Standby Current: 1 μ A

• Available for laminated ceramic capacitor: (Electric capacity 10 μ F or higher)

• On-chip over-current protection circuit

• On-chip thermal shut down circuit

APPLICATIONS

These regulators are suitable for large-scale ASICs which are used in digital appliances etc.
