DESCRIPTION

The

μPC3033 and 3005 are low-saturation type regulators with an output current of 1 A at respective output

voltages of 3.3 V and 5 V. These regulators are also provided with an ON/OFF function, which reduces the dissipation

when there is no load, making them ideal for systems requiring low power consumption. Since output voltage

accuracy is as high as ±1%, it can respond also to the application of which high precision is required.

FEATURES

• ON/OFF pin for output control (active-high)

• Output voltage accuracy: VO = ±1% (when TA = 25°C)

• Output current capacitance: 1 A

• Low dropout voltage: VDIF = 0.6 V MAX. (at IO = 0.5 A)

• On-chip inrush current protection circuit for when input voltage rises (when input

voltage is low level)

• On-chip overcurrent and thermal protection circuit

APPLICATIONS

Digital TV, Audio, Air conditioner, etc.
