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.
